What is Company and Product News: J. Sep. Sci. 3/2007 about?

## Trace H 2 O in Argon GOW-MAC Instrument Company's newest process instrument, the Series 1400 Analyzer, measures trace amounts of moisture in argon. Two models cover different analytical ranges: Model 1400-A covers 0-2/0-20 ppm; Model 1400-B covers 0-20/0-200 ppm. Detection is based on spectral emission of argon plasma. High signal gain and improved noise rejection give the gas analyser a guaranteed sensitivity of 10 ppb for H2O. The analyser is designed as a rugged, low cost, virtually maintenance-free, easy-to-use instrument. There are no valves, carrier gas, or radioactive source. Its features include on-line, continuous trending of moisture concentration with no need for sample injection or separation columns. Exposure to atmosphere or high impurity concentrations does not result in damage to the analytical cell; extreme periods of dryness will not affect response. Patented electro-optical modulation eliminates unwanted noise and drift, generating a modulated signal without the use of a mechanical chopper.
