MAY 2008 SPECTROSCOPY GLOBAL EDITION 27 nology, pharmaceuticals, and materials analysis. The spectrophotometers are constructed with a double-beam optical system and have separate lamps for the visible and UV wavelength ranges. At last year’s Pittcon, Bruker Optics (Billerica, Massachusetts) introduced the Alpha, the low-cost FT-IR system with the smallest footprint of any laboratory-based FT-IR instrument. A unique feature of the Alpha is its QuickSnap interchangeable accessory–sampling modules. This year, the company introduced three new sampling modules: a heated diamond attenuated total reflectance (ATR) for liquid analysis, a diffuse reflectance for powders and gemstone analysis, and a specular reflectance for surface analysis. Bruker Optics also introduced the MultiRAM, a standalone FT-Raman spectrometer. The MultiRAM is a fully automated FT-Raman instrument covering a range of applications from demanding research in academia, industry, and government laboratories to routine nondestructive analysis of both organic and inorganic materials. The dual-channel instrument is equipped with a 1064-nm Nd:YAG laser and accommodates a broad range of pre-aligned sampling accessories, including video stages, high–low temperature cells, fiber-optic probes, and a well plate accessory for highthroughput sampling. The Daltonics NBC division of Bruker introduced the M-IR, a new rugged, fully self-contained mobile (Suitcase style) FTIR analysis system. The system is fully integrated with a single-reflection ATR for easy sampling and cleaning, and it has the provision for an alternative flow-through cell. It is designed to operate between 25 °C and 40 °C. The system includes an embedded PC with a touch-screen user interface, and options for Ethernet, wireless, and USB external connectivity. It is powered via either a 4-h internal (rechargeable) battery or a 12-V power source, such as a vehicle “lighter-style” power connector. It is a fully functional FT-IR, providing normal functionality with the Bruker OPUS/Mentor software. The Daltonics division also introduced the HAWK FR (first responder) a rugged, tripod-mounted FT-IR intended for the homeland security market for lowcost chemical agent monitoring. The HAWK is derived from the RAPID, a milspec version designed for U.S. military applications. A2 Technologies (Danbury, Connecticut) and Smiths Detection (Danbury, Connecticut) both introduced handheld FT-IR systems for material identification via an ATR touch probe. The systems share a common external design, with the version from Smiths Detection, the HazMatID Ranger, being yellow and the A2 Technologies version, the Exoscan, being red. The FT-IR is fully self-contained in a lightweight (approximately 7 lb) pistolgrip style battery-powered (3-h continuous) unit, designed for single-handed operation. It is a fully functional FT-IR system operating between 4000 cm 1 and 650 cm 1 at 4-cm 1 resolution. The sample interface is reflectance based and features an interchangeable ATR–external
