Perma Pure Micro-GASS Heated Gas Sampling Systems for Electrochemical Sensors

Perma Pure's Micro-GASS systems prepare gas samples for analysis by electrochemical sensors (ECS) when samples are hot and too humid for analysis, typically condensing at room temperature. The Micro-GASS system reduces sample humidity to the ideal range for ECS, typically 30 to 70% R.H., while also removing dust or dirt particles from the sample.

The Micro-GASS units rely on Nafion dryer technology and offer full corrosion resistance and very high selectivity, so complex samples can be processed without loss of analyte gases.

Key Specifications

  • Accepts flow rates up to 1 lpm
  • NEMA-4X rated
  • 0.1 micron disposable filter
  • Yields 30-70% RH samples
  • Built-in pump draws sample to sensor
  • Self-contained unit; can be transported since it only relies on a power source
