Series 1200 Analyzer — Trace N2 in Argon
Series 1300 Analyzer — Trace N2 in Helium
Series 1400 Analyzer — Trace H2O in Argon
Each series has two models to choose from covering different ranges:
“A” covers 0-2/0-20 ppm
“B” covers 0-20/0-200 ppm
Detection is based on spectral emission of argon (helium – Series 1300) plasma. High signal gain and improved noise rejection, gives each series the guaranteed sensitivity of 10 ppb for the impurity.
Each analyzer is designed as a rugged, low cost, low maintenance, straightforward instrument to operate. There are no valves, carrier gas, or radioactive source. The analyzer is virtually maintenance-free. Features of the analyzers include on-line, continuous trending of impurity 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; Recovers quickly from high impurity levels; Rapid recovery is enhanced by the unique detector design; 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.
