Membrane Inlet Mass Spectrometry (MIMS) 

Unmatched Mass Spec Technology for Ultra-Low Detection

Powerful Membrane Inlet Mass Spectrometry (MIMS) for Ultra-Low Detection Applications

Membrane Inlet Mass Spectrometry (MIMS) is a powerful tool for ultra-trace detection. Designed for incorporation with MAX300-AIRMAX300-LG, and VeraSpec systems, Extrel’s membrane inlet provides the ultimate sensitivity for low-level detection.  The membrane inlet uses a silicone material to concentrate VOCs relative to the air in the sample. A MAX300 with the membrane inlet has the sensitivity to measure low ppt contamination.

  • The standard LDL for Benzene and Pyrrole improves from 10 ppb to 10 ppt
  • The standard LDL for VCM improves from 20 ppb to 2 ppb
