Pittcon 2006 New Products Review


Spectroscopy
Volume 21, Issue 5, pp. 14-33

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.

Atomic Spectroscopy

410 Hg Analyzer (Buck Scientific, East Norwalk, Connecticut) http://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) http://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) http://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) http://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) http://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).
