  • Measurement of crop protection agent using gas chromatography (GC) or HPLC
  • Separation and determination of cold sludge when brewing beer
  • Soot separation prior to use of gas analyzers
  • Roll filters for automatic air filtration units
  • Application : Used as a membrane prefilter in applications such as the determination of crop protection agent residues by GC or HPLC, in cold sludge determination of beer, in soot separation before gas analyzers and as roll filters in automatic air filtration units. Highly suitable for use in applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved.
