Chemical Filter Testing

Source: M+W Group

Chemical filters are used in a wide variety of applications for the contamination control of ambient and circulating air. Monitoring and filtration are usually done in the ppb range. The laboratory of M+W Products offers comprehensive service for testing new as well as proofing of chemical filter materials that have to meet the highest quality requirements. The development of filter materials is focused on removal of all kinds of acidic, basic and organic substances.

Our laboratory is equipped with several test rigs and air handling units with precise air conditioning for filter tests:

  • Dosage of various test substances for simulating relevant cleanroom contaminations (e.g. SO2, H2S, NH3, NOX, TMB, ozone and others) can be realized
  • Testing of several filter materials: modified charcoal, ion exchange raisins, modified inorganic adsorbent materials and others
  • Online measurement devices as well as offline sampling (impinger method and adsorbent tubes) are available
