MAY 2008 SPECTROSCOPY GLOBAL EDITION 21 ative to Raman. In fairness, PerkinElmer was probably the first company to produce a Raman instrument, the LR-1, back in the late 1960s and early 1970s. It was also one of the first companies to produce an FTRaman system (Nicolet was one of the others). PerkinElmer is now back in the Raman instrument business with its 400 model products — the RamanStation 400 and the RamanFlex 400 — and a Raman microscope, the RamanMicro 200. These are dispersive-based instruments based on an Echelle grating optical system. The RamanStation is a flexible benchtop instrument that offers a wide range of sampling options, including an automated xyz sampling platform for high-throughput well plate reading. The RamanFlex is a fiber-optic–based rack-style system for reaction monitoring and process-related applications. In addition to its new Raman spectroscopy products, PerkinElmer introduced high-throughput sample introduction systems for its ELAN inductively coupled plasma mass spectrometry (ICPMS) system and its Optima ICP instruments. The target applications for the systems are metals in drinking water (EPA methods 200.7 and 2008.) and other environmental applications. PerkinElmer also introduced the latest generation Optima series (7000 family products), ICP elemental analysis instrumentation for environmental, geochemical, product testing, and biofuels applications. In the area of elemental analysis, PerkinElmer has specialized in wear metals analysis for lubricating oils. It has produced the JANUS Oil Prep Workstation for increased automation in capital equipment maintenance. Thermo Fisher Scientific (Waltham, Massachusetts) introduced new FT-IR and Raman products from what used to be its Nicolet stable. A theme of these products was simplification and ease of use. The iS10 FT-IR system is focused on QA/QC and investigative analytical work with simplified data analysis, sample handling, and instrument validation. The company describes the use of revolutionary deconvolution protocols to help simplify and automate the spectral interpretation process, including the identification of individual components of a mixture. On the sample handling side, for convenience, the iS10 enables a user to configure the instrument with two sampling techniques installed at a time. The iN10, an integrated FT-IR microscope, also was introduced. The product is equipped with a high-efficiency room-temperature detector, eliminating the need for and inconvenience of liquid nitrogen cooling. Sample location and measurement are automated by means of machine vision technology, and the OMNIC Picta software can extract comprehensive chemical and physical information, reducing the time required between taking the sample and presenting the answer. Raman spectroscopy is described, in many contexts, as the complementary technique to infrared spectroscopy, and in support of that theme, Thermo Fisher Scientific has introduced complementary Raman products — the DXR Smart Raman spec-
