Chemists are in the knowledge business. Triple-Stage Quadrupole GC/MS/MS/DS system is capable of performing four types of experiments including daughter, parent, neutral loss/gain, and standard GC/MS experiments which yield far greater specificity than GC/MS alone. TSQ has applications in toxic substance analysis, pharmacokinetic/metabolism studies, process control, and formulation. Finnigan MAT 402
Dialog brings knowledge to them. From all over the world. There are a lot of chemists in your field around the world. They publish a lot of information that could be helpful, if only you could get your hands on it. Turn to Dialog. It extends your reach around the world. Dialog is the world's largest online information retrieval system. It has more databases, more abstracts of articles, more references, by far, than any other system. In seconds, Dialog puts you in touch with the latest developments in your field, and it also retrieves information going back 10 years. It places the knowledge of the world at your fingertips. And it's surprisingly low in cost. A search can cost as little as $5. You can search Dialog from a computer terminal in your office. Or your librarian may already be using Dialog.

Carbon Monoxide Monitor
Electronic Balances
Model 3400 is a direct-reading monitor that measures time-weighted average (TWA) concentrations of carbon monoxide during a work shift. The unit is silver-dollar-sized and exceeds OSHA accuracy requirements. 3M 434 FTIR/GC System
Model PE209, with 210-g capacity and 0.01-g readability, and Model PE2000, with 2100-g capacity and 0.1-g readability, feature single-control-bar operation. Other features include a mechanical overload protection device and display of a message if there is overload, underload, or a power-line interruption. Mettler 442
Fx-6221 is a spectrometer system configured both for conventional spectroscopy and on-the-fly detection of gas chromatographic eluents. The 40-cmlong gold-coated light pipe gives full GC resolution. A multiprocessor data system facilitates data collection, Fourier transformation, spectrum display, and data storage in 2 s for full 4 - c m _ 1 resolution spectrum. $50 000. Analect Instruments 446
AtomScan 2000 employs a high-speed drive that can traverse the entire UV/VIS spectrum in less than 1 s. It has a 0.75-m crossed Czerny-Turner optical design which covers a wavelength range from 175 to 800 nm and is temperature-controlled and air-cushioned for stability. Fisher Scientific Co. 443
