Technology Used

  • Oxygen purity measurement – Servomex’ unique paramagnetic cell, which offers a fast, linear, accurate, highly stable and selective response in a non-depleting rugged package.
  • Oxygen at trace levels - Servomex’ unique zirconia cell, which offers an accurate and stable measurement in a design that gives a fast response and exceptionally long service life.
  • Carbon dioxide, nitrous oxide, carbon monoxide* and methane* at trace levels – Single beam gas filter correlation photometric technology, which gives a highly stable, sensitive and selective measurement.
  • Argon in oxygen, Nitrogen in Air and Nitrogen in argon: Thermal conductivity measurement using the patented “TRU REF” technology

Typical Applications

  • Product purity on air separation plant
  • Process control on air separation plant
  • Monitor the trace CO2 on scrubbed air inlet to air separation process
  • Bottling/filling plant applications
