Pages: 28–47

Our annual review of products introduced during the past 12 months, along with an assessment of the overarching trends.

We are pleased to present our annual review of new products. As has been the case for many years now, this annual review includes products launched not only at the annual Pittsburgh conference (“Pittcon”), but also throughout the preceding year.

Nevertheless, Pittcon remains an important source of new product announcements. This year’s Pittcon, however, was held online—a first for the event—because of the Covid-19 pandemic. In the online format, you could attend technical presentations, keynote talks, short courses, workshops, and networking sessions, as well as see exhibitor demonstrations, attend the employment bureau, and—related to our interests and purposes here—you could visit exhibits and talk to exhibitor representatives. The main difference this year was that we couldn’t unexpectedly run into old friends while traversing the halls or aisles. We also could not participate in a “hands-on” demonstration of equipment.

Presumably because of the online format, there was a decrease in the size of the exposition this year (only 179 exhibitors, compared to 787 last year) and the absence of several large vendors. This year, again presumably because of the online format, no product awards were given out.

There was a significant change in attendance at the conference compared to previous years, but we have to acknowledge that we are comparing the “apples” of a live conference with the “oranges” of an online one. The overall attendance in 2020 was 12,841 registered participants. Although it was clear from the live attendance numbers visible in the online platform for this year’s event that the numbers were comparatively quite small this year, generally around 1000 at any given time, official attendance figures for 2021 were not available by our deadline. Because most features of the conference are available on demand through June 12, the conference organization will not have final numbers until then.


The review that follows is categorized by wavelength region or type of spectroscopy. This arrangement is designed to allow readers to compare instruments from different manufacturers, although this process sometimes compares handhelds and other portable instruments with high-end benchtop research tools. Our included categories fluctuate from year to year, depending on trends in new product launches. The categories appearing in this year’s review are:

Atomic spectroscopy


Mass spectrometry

Mid-infrared (Mid-IR) and terahertz (THz) spectroscopy

Near infrared (NIR) spectroscopy Raman spectroscopy






As we have reported in previous reviews, manufacturers have recently been producing instruments that incorporate two or more different, and sometimes disparate, technologies. Given that the number of such instruments has been increasing every year, we considered whether a new approach to this question was warranted. Ultimately, we decided to assign a primary category for each product, but also list potential alternate categories that the product might plausibly be listed under. For an ICP-MS instrument, for example, which could plausibly fit under either the “Atomic Spectroscopy” (for the ICP) or the “Mass Spectrometry” category, we have assigned it to the Atomic Spectroscopy category, but in that table, we show the secondary category in parentheses, in the left-hand column, below the company name, like this:

Company name

(Mass spectrometry).

We also employed a similar label for accessories, indicating the primary technology that the accessory is intended for in parentheses.

As in the past, accessories are tools used in conjunction with an instrument, such as sample preparation or attenuated total reflectance (ATR) devices, whereas components, such as lasers or detectors, are used within an instrument. Yet no matter how we present them, there are always marginal cases, such as where a product is so large and integral to the operation of the analytical system that it is unclear where the concept of an “accessory” ends and an “instrument” begins.

For all of these reasons, even the manufacturer is sometimes unsure about what category a given device belongs to. Sometimes, the distinction depends on the perspective of the observer. An example of this is gas chromatography–infrared spectroscopy (GC–IR). From the point of view of the spectroscopist, the GC is “simply” a very sophisticated sample preparation accessory, although from the point of view of the chromatographer, the spectrometer is “merely” a very complicated detector!

The software category includes programs for instrument control, data collection, and data processing, as well as products for storage and transmission of data. The category also includes collections of data, such as databases (libraries) of spectra, as well as collections of calibration models used in conjunction with the still developing field of chemometric algorithms that analyze the data.

As is our custom, Table I lists the categories that the various companies offer instruments in.

Overview: Broad Trends

Typically, our vendor surveys answer our question about trends in many different ways. The 2021 surveys, however, show a consistent observation about the importance of speed and efficiency. Although similar to comments given over many years, this theme was more noticeable in 2021. Many laboratories downsized or worked with limited staffing in the last year, requiring those who remained to be more productive. Further, as older subject matter experts (SMEs) retired, they were either not replaced or were replaced with less-experienced workers who had little time to gain the benefit of the SMEs’ experience. In addition, those on-site workers were often present in shorter shifts or limited days, as well as performing a lot of remote work, meaning they had to plan and execute their analyses carefully.

These variables resulted in instrument specifications growing more aggressive, with requirements like more automation, intense sources, higher signal-to-noise (S/N), and more-sensitive detectors, resulting in faster data collection. Also, software (particularly the offline analytical type) became even more prominent in instrument sales. Finally, virtual training (both general webinars and instrument-specific training on operations) became very important. Even vendors who did not specifically mention the “faster, more efficient” theme implied this through their product descriptions.

We do not expect this trend will change, even if more people return to the physical workplace for longer hours. The “need” to work at home experienced during the pandemic has transitioned to the “ability” to work at home (as a viable work option, irrespective of need), through various other sharing platforms. Many instruments can now be operated remotely, with autosamplers enabling unattended throughput. Laboratory staff need to be physically present only long enough to set up a batch and start the process; they can then monitor and tweak the process remotely. Even academic teaching laboratories are reaping the benefits of remote instrumentation, because students can now check the progress of a measurement from the library or their dorm rooms.

Another outgrowth of the loss of SMEs has been the emphasis placed on digital science and, more specifically, machine learning. Broadly, this tool enables a system (instrument plus computer plus software) to derive relationships between data and answers that can be reproduced in the absence of human intervention, enabling the system to make “intelligent” decisions about specific characteristics of a sample, such as its usability in a specific application, or an identification based on large datasets. We feel strongly this will be a key driver in the future workspace as the machine learning algorithms improve and become more broadly applicable (consider how online shopping proposes new things based on your past choices; the same logic can be applied to a production process).

We see fewer application-specific analyzers appearing this year, although some fields, like cannabis and microplastics, are attracting attention. In many cases, existing tools are being combined with new software to address these fields, such as the innovations from multiple vendors implementing microplastics analysis onto Raman, FT-IR, and quantum cascade laser (QCL)–based microscopy systems.

Handhelds and portables continue to appear, but not with the same ubiquity as a few years back when we noted every aisle at Pittcon seemed to have a handheld Raman or NIR tool on display. Many articles have appeared in the literature, and in this journal specifically, about the benefits of the handhelds and portables. There has been less discussion about the performance differential between handheld and laboratory instruments; however, this difference is largely driven by the different purposes and applications of the two types of instruments (“What is this pile of white powder? Is it dangerous?” versus “I need to analyze a tiny defect in a sheet of polymer or discolored flecks in an otherwise homogeneous product”).
