Series 1300 Trace Nitrogen in Helium Analyzer

GOW-MAC® Instrument Company (Bethlehem, PA, USA) introduces their newest process instrument, the Series 1300 Trace Nitrogen in Helium Analyzer.

Two models cover different analytical ranges: Model 1300-A covers 0-2/0-20 ppm; Model 1300-B covers 0-20/0-200 ppm. Detection is based on spectral emission of helium plasma. High signal gain and improved noise rejection, gives the Series 1300 the guaranteed sensitivity of 10 parts-per-billion (ppb) for nitrogen.

The Series 1300 is designed as a rugged, low cost, low maintenance analyzer. There are no valves, carrier gas, or radioactive source. The analyzer is maintenance-free. Features include on-line, continuous trending of nitrogen 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; 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, generating a modulated signal without the use of a mechanical chopper.
