Emil Ciurczak presents his review of the newest and most interesting products in the field of spectroscopy at the 2006 Pittcon Conference.
Greetings from Orlando. I was asked to share some of the new spectroscopic products to be exhibited at Pittcon 2006. It's a busy time for vendors, but a few were willing to take the time to share some info with us. The hardware and software listed are by no means all the goodies shown, just what we were given to write about.
I don't want any vendor to feel slighted, but, the editorial staff asked for submissions weeks and weeks before the show... and it was still coming in April! Here's what we have to share.
While I was to divide the materials into Atomic, Molecular, and Mass Spec, there had to be some compromises. For example UV–vis is now under "Molecular." In any case, here is what I received.
410 Hg Analyzer (Buck Scientific, East Norwalk, Connecticut) www.bucksci.com: The 410 is a dedicated cold vapor system with a 400-mm Quartz flow cell. It can print directly to a printer, making it CFR 21 compliant. Excellent for trace Hg analysis in water, it offers the lowest detection limits of Hg for less than $10,000.
PTFE and PFA Spray Chambers (Glass Expansion, Inc., Pocasset, Massachusetts) www.geicp.com: This accessory is for ICP-AES and ICP-MS. It features cyclonic spray chambers of high purity and inert materials. It can be used for ultratrace analyses by ICP-MS and analysis of HF containing samples by ICP-AES or ICP-MS. It boasts higher transport efficiency and better precision and has a chemically treated interior surface to enhance the interaction of the sample with the chamber. Helix o-ring-free nebulizer fitting facilitates nebulizer installation and removal and decreases carryover.
Niagara Rapid Rinse Accessory (Glass Expansion, Inc., Pocasset, Massachusetts) www.geicp.com: Another accessory for ICP-AES and ICP-MS, it is a standalone device that mounts in the kitchen area of ICP-MS or ICP-AES. The spectrometer consists of programmable two-way valve that eliminates the sample washout step. All applications of ICP-AES and ICP-MS are run in an unattended manner. It reduces the analysis cycle by 15 to 35%, resulting in greater instrument productivity. The accessory has an adjustable height stand to maximize fast washout. It uses a serial connection to the autosampler to allow use with a wide variety of ICP-AES and ICP-MS models.
SPECTRO Genesis ICP (SPECTRO Analytical Instruments, Inc, Marlborough, Massachusetts) www.spectro.com: A new CCD-ICP-OES spectrometer was introduced. It comes supplied with factory-installed methods. Its suggested applications include environmental testing. Because it is factory calibrated, it should be simple to operate.
The CETAC Aridus II system (CETAC Technologies, Omaha, Nebraska) www.cetac.com: A specialized desolvating-nebulizer for ICP-MS. The Aridus II couples a low-flow PFA nebulizer and spray chamber with a fluoropolymer membrane for maximum chemical resistance (including organics and HF). Benefits include enhanced analyte sensitvity and greatly reduced solvent-based interference (i.e., oxides and hydrides). The CeO/Ce ratio is typically < 0.03%. New features include alleviation of electrostatic effects and the ability to handle higher uptake rates (to 200 μL/min).
The CETAC M-8000 Mercury Analyzer (CETAC Technologies, Omaha, Nebraska) www.cetac.com: This instrument is designed to make some of the most rigorous methodologies simple. The QuickTrace software ensures the validity of calibration techniques by EPA 1631 and 245.7 methods. It can be switched easily from high-concentration analysis to ultratrace analysis with the use of gold traps. The system employs a nonfoaming gas–liquid separator (GLS) for extraction of mercury vapor from liquid. Automated calibrations, sample analysis, quality control, and report generation are built in, satisfying the most demanding sample throughput and quality control requirements. Components of the M-8000 are easily accessible for user maintenance.

The laser output energy is fully adjustable to produce varying amounts of ablation to analyze virtually any solid sample. The laser and optics are thermally and mechanically isolated with no protruding parts, so laser and optical alignment will stay for the lifetime of the system. The built-in mass flow controller allows precise control of helium flow for consistent sample transport into either the ICP-AES or the ICP-MS.
Prodigy-H (ICP-OES), (Teledyne Leeman Labs, Hudson, New Hampshire) www.LeemanLabs.com: The Prodigy-H is designed to permit the measurement of the halogen elements at the same time as the more routine metal measurements. It incorporates all the features of the Prodigy model, but with a deep UV-sensitive detection system for unprecedented wavelength coverage from 134–1100 nm.
The instrument allows analysis of analytes that normally required techniques such as ion chromatography or ion selective electrodes. It measures Cl, Br, and Iodine at sub-ppb levels along with all of the conventional metals.
Prodigy-Mobile Lab (Teledyne Leeman Labs): Good for lab or process applications, this transportable simultaneous ICP spectrometer is named the Prodigy-Mobile Lab. By providing accessibility to laboratory quality ICP-OES instrumentation, the Prodigy-Mobile Lab can accelerate data collection, reduce the cost of producing it, and help to make decisions about site characterization. The engineers worked with truck and trailer manufacturers and remediation companies to determine the hazards associated with on-site transportable operation. Its integral suspension system works with parent vehicle's suspension, isolating the instrument from drive train, road, and shock hazards. The result is laboratory-quality data for in-field operation.
Hydra C (Teledyne Leeman Labs): Another lab or process instrument is the Hydra C, designed for analysts who want to use EPA's new method 7473 or to determine mercury in their sample without prior sample digestion. The Hydra-C employs the optical designs of earlier continuous-flow analyzers, coupled with gold amalgamation purge-and-trap preconcentration to achieve high sensitivity and low noise. It uses Windows 2000 programming and is fully automated, with computer control of all instrument parameters and functions. An on-line balance is available for electronic sample weight input. It is a direct combustion mercury analyzer, available with cold vapor atomic absorption (CVAA) or cold vapor atomic fluorescence (CVAF). CVAF provides for lower limits of detection and longer dynamic range than CVAA. Hydra-C combusts the sample to release mercury vapor. Solid and liquid samples are loaded onto Hydra-C's autosampler and analyzed without acid digestion. The combustion process does not require the conversion of mercury to mercuric. There is no need for reagents such as strong acids, oxidizers, and reductants or hazardous waste to be disposed of. The Hydra-C can reduce both analysis time and cost.
Prism ICP (Teledyne Leeman Labs): Teledyne Leeman Labs has expanded its product line with the new Prism ICP, a high-performance simultaneous ICP that incorporates their most recent innovation in solid-state detection, the C-PAD (Composite Programmable Array Detector). It is designed to generate accurate results fast at a low price. Like all Leeman Echelle spectrometers, Prism was designed with attention to optical performance. With its long focal length Echelle spectrometer provides the spectral resolution needed for interference-free measurements along with the stray light rejection needed to ensure low detection limits in complex sample matrices. Prism's C-PAD simultaneous detection system offers access to a vast array of wavelengths between 177 and 900 nm and provides independent in-pixel processing so signals for all wavelengths are optimized automatically; intense emissions do not saturate the detector and less intense emissions have minimal read noise. This means Prism provides exceptional linear dynamic range together with very low limits of detection. The Prism is available in Axial, Radial, or Dual View configurations to offer the versatility needed to today's broad range of applications.

Poseiden-5000 (Axiom Analytical, Irvine, California)www.goaxiom.com: This instrument is based upon the sparging infrared technique, making possible the use of a vapor phase measurement to analyze liquid concentrations. The discharge of organic chemicals into the water is an endemic problem at most large chemical manufacturing plants. Such plants generally employ remediation facilities to purify their wastewater before discharging it into the environment.
Conventional detection methods typically involve slow techniques such as GC or GC–MS. The sparging infrared technique takes advantage of the fact that the concentrations of pollutant vapors in an air vapor stream being sparged through a volume of water will be in equilibrium with the liquid phase concentrations in the water. Measurement of the vapor concentrations can be performed quickly and easily by using FT-IR spectroscopy. The wastewater analysis system usually will be calibrated to report on those volatile organics that might be present in a given plant environment, a small number of components. Axiom has measured as many as 15 different species simultaneously during lab simulation. In routine operation, the measured concentrations will be reported via the plant's network. For analytical purposes, the time-dependent depletion curves can be monitored on the system's monitor.

FFM Series gas cells for NIR (Axiom Analytical, Inc., Irvine, California), www.goaxiom.com: Highly sensitive near-IR analysis of vapors has been made possible by the advent of tunable laser spectrometers and the development of specifically designed long-path gas cells. One key element is the spectral radiance of the tunable laser source. A second important element is the laser's high coherence. This has paved the way for long path gas cells (the FFM Series), which are said to be more robust than the White cells typically used by FTIR and dispersive instruments. The performance of FFM Series gas cells is possible because of the degree of mechanical precision and robust materials (fused silica and stainless steel) in contact with the process stream. These are combined with an optical design that allows the cell to be aligned while being assembled by using a fiber-coupled visible laser source. The FFM cell can be disassembled, cleaned with common solvents, reassembled, and realigned in minutes. The FFM highly is suitable in applications such as dryer off-gas monitoring where upset conditions can occasionally coat the interior of the cell with powders or other contaminants.

FPT-855 Near-IR Transmission Probe (Axiom Analytical, Inc.): This instrument features an integral heating jacket that eliminates fouling due to the condensation of product on the probe surfaces. It also shares the robust qualities of the company's FPT-850 extreme duty probe. This probe was developed to provide maximum long-term reliability under the extreme conditions of high temperature, thermal shock, and aggressive chemistries encountered in many on-line process applications. A key element is a proprietary sealing technique involving a direct sapphire to Hastelloy welded pressure seal. A high degree of chemical resistance is assured by the fact that the only materials in contact with the process are sapphire, Hastelloy, and a thin flash of either gold or PTFE (application dependant). The compliance required to withstand extreme temperature cycling is provided by the Hastelloy seal, which is compressed at high pressure prior to welding. This approach eliminates fatigue and stress failures common with brazed seals. Finally, the elimination of elastomeric seals provides for reliable long-term operation at temperatures as high as to 400 °C.
