Series 1400 Trace H₂O in Argon Analyzer

GOW-MAC^® Instrument Co. (USA) introduces the Series 1400 Analyzer for measuring trace amounts of moisture (H₂O) in argon. 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 gives the Series 1400 the guaranteed sensitivity of 10 parts-per-billion (ppb) for H₂O.

The analyzer is a rugged, low cost, low maintenance, straightforward instrument to operate. There are no valves, carrier gas, or radioactive source. Features of the Series 1400 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 acute dryness will not affect response or detector; Cannot “blind” the instrument; Recovers quickly from high moisture levels; No permanent degradation of detector due to high moisture levels; Over-range protection eliminates possibility of false readings caused by high impurity plasma quenching; A non-depleting cell for extended operation provides long life and is maintenance-free; Patented electro-optical modulation eliminates unwanted noise and drift, generating a modulated signal without the use of a mechanical chopper.
