Detection of volatile compounds

E-NIMS

Sensitve detection of airborne molecular contaminations

The ion mobility spectrometer E-NIMS is an advanced analytical device for fast and reliable trace detection of volatile compounds in industrial environments. E-NIMS combines state-of-the-art ion mobility spectrometry with an innovative non-radioactive ionization technology. A specially tailored electron beam source offering high stability, pulsed mode operation and intensity control enables efficient ionization and outstanding performance. With the E-NIMS, elaborate licensing, regulatory supervision and disposal of radioactive material, as it is necessary for most conventional ion mobility devices, belongs to the past.

Key features

  • Direct ppb measurement of airborne molecular   contamination (AMC)
  • Approved IMS technology
  • Non-radioactive ionization by stable electron beam
  • No X-ray licensing required
  • Fast response and cleardown
  • No interference from acid gases and halogens
  • Continuous, unattended monitoring
  • Optional multipoint sampling

    Applications

      • Continuous emission monitoring of ammonia (NH3) in ambient air
      • Detection range: 0-50 ppb, Lower Detection Limit (LDL): 2 ppb
      • Cleanroom air and process monitoring, e.g., in semiconductor industry or optical goods industry
      • Determination of further molecular bases (amines, NMP), molecular acids and halogens (on request)
