Simple trace N2O detection in inert gases

With the HALO 3 N2O, powerful advanced spectroscopy is available for a host of applications, from process control to quality and safety assurance in Air Separation Plants. Other applications include monitoring of cylinder filling, bulk delivery and distribution transfer points, as well as welding, medical, industrial and high-purity gas production, and more. Say goodbye to cumbersome, complex, costly and labor-intensive mid-20th century technology. Gone is the need for calibration, spare parts, limited measurement ranges, and worries about drift and downtime usually associated with NDIRs, FTIRs, or GCs.

Designed for trace level nitrous oxide analysis, the HALO 3 N2O offers:

  • Sub-parts-per-million (ppm) N2O detection capability
  • Absolute measurement (freedom from calibration gases)
  • Wide dynamic range—over four orders of magnitude
  • Low cost of ownership and operational simplicity
  • Clean technology—no external calibration gases required
  • Compact analyzer footprint
  • User-programmable alarms immediately notify on high events

Applications

  • Gas Quality Control
  • Gaseous CRMs & Calibration Gas Mixtures
  • Research & Development
