Gow-Mac Instrument has introduced its latest process instrument, the Series 1200 analyser.
Gow-Mac Instrument has introduced its latest process instrument, the Series 1200 analyser.
This gas analyser measures trace amounts of nitrogen in argon.
Two models cover different analytical ranges: Model 1200-A covers 0-2/0-20ppm, while Model 1200-B covers 0-20/0-200ppm.
Detection is based on spectral emission of argon plasma.
High signal gain and improved noise rejection, gives the Series 1200 the guaranteed sensitivity of 10ppb for nitrogen, says the company.
The Series 1200 is designed as a rugged, low-cost, low maintenance, simple to operate analyser.
There are no valves, carrier gas, or radioactive source.
The analyser is maintenance-free.
Other 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, and 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.
Relevant applications include air separation plants, argon purification plants, cryogenic truck loading stations, speciality gas laboratories, process control, new line certification, cryogenic steel manufacturing, chemical plants, gas management/monitoring systems, quality control for truck fills and gas cylinders, welding gas management, and semiconductor manufacturing.
