30 SPECTROSCOPY GLOBAL EDITION MAY 2008 in 1–30 s. It is designed for external operation over a range of 40 °C to +60 °C. The Site Protector software provides threat evaluation, gas identification, concentration, and time stamp. Two state-of-the-art instruments were presented by SPECTRO (Mahwah, New Jersey); the new ARCOS (Advanced Roland Circle Optical System) ICP optical emission spectrometer, and the SPECTRO iQ II X-ray fluorescence analyzer. The optics of the ARCOS utilize 32 linear CCD array detectors for the simultaneous recording of wavelengths between 130 nm and 770 nm. This, combined with a 750mm focal length, makes the system ideal for ultratrace analysis for environmental applications, for line-rich spectra in metals analysis, and for organic materials in petrochemistry. The iQ uses polarized Xray excitation and is developed for multielement analysis of solids, powders, and liquid samples. Typically, it is used for industrial process applications. Agilent Technologies (Santa Clara, California), like many of the other larger instrument companies, is orienting itself toward markets and applications. The Materials Science Solution Unit (MSSU) has been added to the company. Its mission is to primarily offer nano-measurement solutions and support to accelerate discovery, manufacture, and commercialization of high value materials. The applications covered are high-tech research, pharmaceuticals, specialty chemicals, food safety, biotechnology, and semiconductors. The technology platforms include UV–vis spectroscopy, scanning probe (atomic force) microscopy, particle analysis, and high precision interferometry and optics. In addition to MSSU, Agilent continues to develop a strong product offering in mass spectrometry, including new Accurate-Mass time of flight (TOF) and Accurate Mass Quadrupole Q-TOF products. The 6220 (Accurate Mass TOF) liquid chromatography (LC)–MS system offers better than 2-ppm mass accuracy combined with 20,000 mass resolution and high-speed (32 GBit/s) data acquisition. Although not thought of traditionally as infrared, we are starting to see products on the market based on cavity ring down spectroscopy (CRDS) and related technologies. These laser-based systems utilize the inherent high-resolution capability of the laser to provide unique analyses for industrial and environmental applications. Although intrinsically high resolution, they have low drift and excellent sensitivity, and are essentially calibration free, making them ideal for process analytical applications. Two new products from Picarro are based on this technology — the G1101-i isotopic CO2 analyzer and the G1102-i isotopic H2O analyzer. The CO2 analyzer is well suited for detecting greenhouse gas emissions. While on the topic of the environment, albeit briefly, mercury analysis and mercury emissions remain highprofile applications. Milestone, Inc. (Shelton, Connecticut) has introduced an atomic measurement system for
