PG28L Purge Gas Generator

The PG28L gas generators from Peak Scientific are suitable for laboratory detectors requiring CO2 free gas such as FT-IR analysis. Using Pressure Swing Adsorption technology to remove organic contaminants and moisture from air, these generators provide a consistent flow of air to ensure little background noise in laboratory analysis.

Requiring minimal maintenance, the PG28L does require an external source of air to operate, Peak Scientific will be able to help with recommending a suitable air source if your laboratory does not have one.

  • Purge Gas (PG) generators from Peak Scientific produce air which is free of CO2
  • Ideal for commercial labs with a high throughput rate of samples
  • High performance filters and PSA ensure maximum reduction of moisture (< -70ºC dew point).
  • Few moving parts means minimum maintenance requirements and 24/7 performance
  • Position generator where required, wall mountable for small labs
  • More cost effective than any other gas supply as the FT-IR detector needs a constant flow of gas
  • Completely silent in operation
  • 12 month full comprehensive on-site warranty
