Our annual review of new spectroscopy products introduced at Pittcon, or during the previous year.

Our annual review of new spectroscopy products introduced at Pittcon, or during the previous year.

In this annual review, we present new spectroscopy instruments, components, and accessories, and we assess the underlying trends.

The Pittsburgh Conference (Pittcon) remains an important venue for the introduction of new products, and the majority of the products listed here are from companies we visited at that conference. In addition, vendors are increasingly announcing new products independently of Pittcon; therefore, this review also includes products launched at other conferences or independent of any tradeshow in the last 12 months.

A welcome surprise is the increase in Pittcon attendance compared to last year. Total attendance was reported as 14,144, compared to 12,841 last year. We are pleased to report the increase, and consider it to bode well for Pittcon’s future.

The exposition featured 787 exhibiting companies occupying 1404 booths, somewhat lower than last year despite the higher total attendance. Of these companies, 124 were reported as being first-time exhibitors. Perhaps the increased attendance will persuade more new companies to exhibit in the future, as well. A breakdown and comparison with previous Pittcons is available on the Pittcon website at

Last year, Pittcon did not present the Editor’s Choice awards that it had presented for many years previously. This year, those prizes were replaced with the Pittcon Today Excellence Awards. Details of the selection process are largely unknown, except for an issued statement that the selection committee consisted of a “blue chip panel of experts” who evaluated the entries based on “ingenuity, creativity, implementation, and outcomes.” Entries were divided into three groups based on corporate sales figures, allowing companies to compete with others of a similar size. There were three awards (gold, silver, and bronze) in each class, for a total of nine awards. We are pleased that one atomic spectroscopy and one mass spectrometry instrument were winners in this competition: Elemission won a silver award for its Mission:Coriosity laser-induced breakdown spectroscopy (LIBS) analyzer and Waters Corporation won a gold award for its Acquity QDa mass detector.

The review that follows is organized by wavelength region or type of spectroscopy (such as Raman, X-ray, and so forth), with accessories, components, and software at the end. We arrange our review to allow readers to compare instruments from different manufacturers, although this process sometimes groups handheld instruments with high-end research tools. The categories used to classify the products are


Atomic spectroscopy


Mass spectrometry (MS)

Mid-infrared spectroscopy

Near-infrared (NIR) spectroscopy

Nuclear magnetic resonance (NMR)

Raman spectroscopy

UV-visible spectroscopy






Categories change from year to year, depending upon trends in the submissions. The core spectroscopy headings are consistent, but “imaging” has been transient. In our taxonomy, “accessories” and “components” are inherently general categories. The dividing line between them is this: “Accessories” (such as a sampling device) are used with an instrument, whereas “components” (such as a laser source or detector) are part of an instrument. The “software” category is focused on software developed independently from the instruments, rather than on software built to drive a particular instrument. The software category also includes products like spectral databases and libraries.

Broad Trends

Three broad themes emerged from this year’s new product review. First, in spite of their age, many of the classic techniques saw activity. For instance, many manufacturers have launched tools for the age-old problem of sample preparation and introduction (grinding and pressing samples) and there were new offerings in inductively coupled plasma (ICP) instruments and Fourier transform infrared (FT-IR) microscopy. There should be little surprise here; many of the problems faced by today’s laboratory workers are the same as those from 20–30 years ago. In spite of exciting developments at the cutting edge, there is plenty of basic chemistry still needing to be done.

Second, although many vendors are marketing instruments similar to those from years past, there is a surge in new software developments. Developments center on two problems: matching the user interface to the problem and lowering sampling barriers. Enlarged databases and new algorithms are combining to provide customized, useful reports. Terrain-following software in microscopy is relieving the problem of focusing on an irregular sample over a large area. And collaboration is being enhanced using video cameras and touch screens to replace single-user eyepieces, allowing local and remote users to tackle problems as a team.

Third, Raman spectroscopy offerings continue to expand. At Pittcon, it seemed every aisle had Raman vendors differentiating their products by size (handheld, portable, or benchtop) and performance. The Raman effect was first observed in 1928, so Raman has had a long development cycle. This was because of some very specific requirements that had to be met to make Raman a commercially viable technique. The most crucial tool has been the laser, and now many vendors provide multiple diode laser solutions in small packages with low power needs. Vendors can take the ingredients-lasers, miniaturized diffraction elements, and multichannel detectors-and combine them in a particular form factor to address a specific market.

There are also a few smaller-scale trends that we see. We noted a trend a few years back toward applications-specific analyzers. While this seems to have slowed, many vendors have noted how their tools combine in certain markets. Instruments targeted to the analysis of gemstones, oil, water, and gases are seen this year.

This year we have also noticed some coupling of different types of instruments. Bruker has combined terahertz and FT-IR spectrometers into a single unit. Thermo Fisher Scientific has a Raman spectrometer specifically engineered to be integrated with other analytical tools. Two or three examples do not a trend make, but this is an area to keep an eye on in the future.

This Year’s Products

In each section of the review, we briefly mention all the products and some salient features. In this discussion, some attempt was made to place similar products with each other rather than strictly alphabetically. In addition, an alphabetical table then provides a summary of all the products in that category.


As in the past, it is inevitable that some categories include products that might arguably be classified elsewhere, especially in regards to accessories, components, and software. Even some hyphenated techniques, such as inductively coupled plasma–mass spectrometry (ICP-MS) could legitimately be listed in either location.

“Imaging” represents a unique challenge. Some imaging instruments (such as Raman imaging instruments) will be found under the corresponding technology. Alternately, readers can search by company name or product category in Table I, which references the headers where the content will be found.


Atomic Spectroscopy

This year in the atomic spectroscopy category (Table II), there are new products from seven companies, of several types.




LIBS continues to make inroads. Atomtrace has a LIBS instrument with double-pulse DPSS laser and a high-resolution echelle spectrometer with an EMCCD/iCCD detector. Elemission’s Coriosity instrument is the most advanced benchtop LIBS analyzer for elemental imaging and analysis currently on the market, and won a silver Pittcon Today Excellence Award. LTB Lasertechnik’s double echelle monochromator, ideal for use with LIBS, provides increased resolution.

Four new plasma spectrochemistry instruments were launched this year. PerkinElmer has the smallest ICP instrument on the market, with patented Flat Plate plasma technology that reportedly uses half as much argon as other systems do. PerkinElmer also introduced the NexION 2000 ICP-MS system, which is designed to handle high total dissolved solids as well as high- and low-level elements in a single sample. Thermo Fisher Scientific has launched a triple-quadrupole ICP-MS system. This system allows users to easily switch between single- and triple-quadrupole modes in one method so that laboratories can keep their existing workflow as well as add new capabilities over time. Nu Instruments launched its third-generation multicollector ICP-MS (MC-ICP-MS) instrument. A new torch box design in this instrument allows easy connection of a wide range of sample introduction devices, and an additional lens element can be inserted to improve abundance sensitivity performance.

The trend to miniaturized systems also continues. Spectro’s handheld arc/spark optical emission spectroscopy (OES) metals analyzer is designed to accurately analyze elements like C, P, S, B, Li, Be, Ca, Si, Mg, and Al at low and critical levels and reportedly is as fast as a handheld X-ray fluorescence (XRF) instrument. Spectro also provides an oil analyzer based on the same principles.


Many imaging instruments (Table III) will be found under the corresponding technology. This section presents two imaging instruments which, for various reasons, were not placed elsewhere.



Bayspec presents two multispectral cameras. One operates in the visible–NIR spectral region; the other uses “pushbroom” technology.

Daylight Solutions imaging spectrometer is designed to provide ultrafast spectral data collection based on tunable quantum cascade laser technology, enabling high-throughput applications without cryogenic cooling, which means only minimum maintenance is required.

Mass Spectrometry

This year we were surprised at the increase in the number of companies exhibiting mass spectrometers or MS-based analyzers compared to last year. Increased sensitivity was targeted by several vendors in the category (Table IV), but the most prevalent trend seemed to revolve around compactness. With the high-end market reasonably saturated, compactness offers a point of entry for new players, with tighter application-specific targeting.




Bayspec has two new portable mass spectrometers. One uses miniature linear ion trap technology with higher sensitivity; the other is a lighter-weight version for easier use in the field. Hiden has a self-contained, automated, secondary ion mass spectrometry (SIMS) tool for routine and repetitive surface analysis.

Extrel has a quadrupole mass spectrometry–based gas analyzer. The use of ion mobility technology enables the Excellims instrument’s use at atmospheric pressure.


In mid-IR (Table V), process monitoring was the target of several vendors. This group of offerings includes a new sensitive gas detection system from Gasera; in addition to general-purpose gas analyzers, Gasera also has a gas analyzer for real-time monitoring of trace-level formaldehyde at extremely low concentrations using built-in automated gas exchange and a quantum cascade laser-an exciting new development. California Analytical Instruments demonstrates a FT-IR gas analyzer that is a versatile instrument and can measure more than 40 gases simultaneously without using liquid nitrogen. Keit has the newest version of a rugged, vibration-tolerant FT-IR spectrometer made for monitoring industrial processes in situ and can be mounted directly onto, or in line with, manufacturing equipment.



In spite of the surge in Raman spectroscopy, the FT-IR microscope still remains a solid and important tool for basic analytical work. IR microscopy was addressed for both basic and advanced users this year. Thermo Fisher Scientific approached the most basic users with the Nicolet iN5 microscope, which has point-and-shoot simplicity. This feature enables fast identification of microscopic unknowns such as defects and contaminants that affect product quality and processes. Shimadzu has a fully automated IR microscope that is designed to perform all steps in microanalysis quickly and easily with a 30,000:1 signal-to-noise ratio (S/N), yielding low-noise spectra for even the smallest contaminants. Daylight Solutions showed an updated quantum cascade laser (QCL) microscope.

Some manufacturers are showing combined technologies, as mentioned in our discussion of trends. Bruker has a combined FT-IR and terahertz spectrometer. In this system, atmospheric artifacts are completely avoided by vacuum systems, enabling coverage from <3 cm-1 (<100 GHz) up to the UV region without cryogenic cooling.
PAC provides a rapid fuel analyzer for gasoline, diesel, and aviation fuel.


This year, compact benchtop and handheld analyzers took center stage in the NIR category (Table VI).



Galaxy Scientific is offering a portable transmission and integrating sphere FT-NIR instrument that offers portability combined with high spectroscopic performance for direct calibration transfer without the frustration of standardizing instruments.

Si-Ware Systems introduced a solid-state FT-IR NIR new compact benchtop spectrometer based on microelectromechanical systems (MEMS) technology.

Spectral Evolution has an ultrahigh-resolution portable spectroradiometer with a spectral range of 350–2500 nm. Its spectral resolution is 1.5 nm at 700 nm, 3.0 nm at 1500 nm, and 3.8 nm at 2100 nm.

A new NIR benchtop spectrometer from tec5USA expands upon the previous platform, including embedded control that eliminates the need for an external computer.

Avantes has a compact benchtop instrument with a new linear array InGaAs detector system based on a 100-mm optical bench with a numerical aperture (NA) of 0.13, offering optical balance between resolution and sensitivity.


Recent years had seen a number of vendors touting new benchtop NMR units. This year, only Magritek announced anything new in this arena, and other vendors did not even show NMR instruments at Pittcon. Whether this is a trend or simply a slow-down remains to be seen. See Table VII for the details.





Raman spectroscopy (Table VIII) remains an area of considerable growth and change. Developments were visible around both the small form factor (AcuTech, Metrohm) and benchtop systems (WITec, Bruker). The availability of new lasers, spectrographs, and detectors has allowed size, sensitivity, and speed to be tuned for specific applications, from raw material identification to ultrafast imaging. Thermo Fisher Scientific offered a compact Raman system designed to hyphenated with tools such as X-ray photoelectron spectroscopy (XPS) or rheometry.



Software enables an instrument to conform to the target markets. The simplest-raw material identification-powers handhelds in loading dock situations. High-end imaging is being augmented with 3-D viewing software and terrain-following image software (WITec), which negates the need to stop and autofocus at each point. This approach has removed a significant barrier; now, the sample needs not be perfectly smooth or level.

We provide some highlights of the individual instruments below.

Acutech has a general-purpose Raman spectrometer as well as a specialized version for gems and an automated version that works under robotic control.

WITec’s TrueSurface module for topographic confocal Raman imaging enhances the power and user-friendliness of confocal Raman microscopes. Raman topographic imaging now features one-pass simultaneous operation. Rough, inclined, or irregularly shaped samples can be investigated with the same ease as standard samples.





A key theme for UV–vis spectroscopy (Table IX) this year continues to be minimization of sample volume and the overall spectrometer. This minimization of the instrument is lowering the cost of such systems and providing new functionality in tiny spectrometers: Most include Raman and fluorescence capabilities in addition to UV–vis. Additionally, microvolume UV–vis continues to be a theme.


Below are some of the highlights of the this year’s UV–vis offerings.

Avantes combines an ultralow-stray-light design, a thermoelectric-cooled back-thinned detector, and a new electronics board to provide a device capable of resolution down to 0.2 nm without sacrificing sensitivity.

Distek eliminates sampling by measuring directly in the dissolution vessel, thus also eliminating problematic filters, tubing, and pumps used in conventional sampling.

VUV Analytics has a next-generation vacuum ultraviolet (VUV) benchtop spectrometer. Used as a gas chromatography (GC) detector, this instrument provides the easy identification and quantitation of compounds without the need for chromatographic baseline resolution, including coeluted analytes and structural isomers.


The vast majority of announcements for new X-ray devices (Table X) called out “benchtop” as a feature, in both diffraction and fluorescence modes.

Software (Table XI) touches all aspects of the analytical lab data stream: system validation, and data collection, processing, analysis, and reporting. Additionally, networking and data management (in laboratory information management systems, or LIMS) are concerns. Many new products announced in 2017 touch on these aspects. Surprisingly, we did not see any new validation products, although recent actions by the U.S. Food and Drug Administration (FDA) indicate a tightening of enforcement. Within this diversity, two important themes are evolving. First, customer problems are being addressed with features such as terrain-following software, improved searching of mixtures, and user friendly workflow-development (macros).



Second, collaboration is being enhanced through video capture and networking. These features permit remote control of an instrument from a home office or enable multiple scientists to view and discuss data live, not just as part of a report. Our experience in dealing with customers worldwide indicates remote control capability is growing in importance, as problems arise in a location remote from the core analytical expertise.

WITec’s Suite Five is an intuitive operating system for all WITec microscopes. It includes a powerful software environment for data acquisition, evaluation, and processing of even large data volumes and 3D scans.


Most accessories (Table XII) announced this year represent evolutions in design rather than wholly new approaches, probably responding to specific customer requests. Big samples are addressed for FT-IR by lifting the sampling plane out of the spectrometer (PIKE), and multiple innovations around sample introduction for ICP (Glass Expansion) addressed temperature of introduction and cleaning. It was very interesting that the hoary old problem of solid sample preparation (grinding and pellet formation) was addressed by multiple vendors, showing that in spite of massive technical revolutions like attenuated total reflectance (ATR), grinding and pressing remains important. And speaking of ATR, recent years saw multiple diamond ATR accessories being introduced whereas this year’s offerings are quiet on this front. Below are highlights of each vendor’s offering.
