Identification, quantification and purity of active ingredients in pesticides, technical materials (TC) and technical concentrates (TK)

Gas Chromatography coupled to Mass Spectrometry (GC/MS)

LEARN MORE

  • Most recommended method to separate and analyze volatile organic compounds (boiling point < 250ºC).
  • Most widely applied chromatographic technique and with greater versatility in the analysis of environmental pollutants.
  • TCD detectors for analysis of inorganic gasses and FID detector for identification of unknown organic components in mixtures and quantification of concentration or purity.
  • With a library of more than 10,000 identifiable compounds

Ultra High Performance Liquid Chromatography (UHPLC)

LEARN MORE

  • Its application is highly occupied in non-volatile and thermally unstable organic compounds.
  • Diode Array Detector (link) The continuous beam of light passes through the cell. The radiation is then resolved into its constituent wavelengths which are individually detected by the diode array.
  • Higher chromatographic resolution in complex mixtures.
  • Higher sensitivity in mixtures with low analyte concentrations.
