Chemical analysis of insecticidal nets

Chemical analysis of insecticidal nets

WHO Collaborating Centre for Quality Control of Pesticides (Bel-38). Laboratory certified in accordance with the OECD Principles of Good Laboratory Practices (GLP) and several analytical methods accredited in accordance with the requirements of the ISO 17


  • Development and validation of analytical methods for determination of active substances in insecticidal nets (and other substrates)
  • Physico-chemical characterization of Long-Lasting Insecticidal Nets (LNs)
  • Appearance (visual description)
  • Total active substance content
  • Isomers or impurities content
  • Fabric weight (mass of net per m²)
  • Within-net and between-net distribution of the active substance
  • Active substance wash resistance (retention / release characteristics)
  • Accelerated storage stability
  • Physical tests (sub-contracting to a WHO recommended laboratory)
  • Quality Control of Long-Lasting Insecticidal Nets (LNs) according to WHO specifications
  • Pesticides analysis in insecticidal nets and other treated substrates (filter papers, wall scrapings, tarpaulins, textiles …)


  • Gas Chromatography :
  • with Flame Ionisation Detection (GC-FID)
  • with Electron Capture and Nirogen Phosphorous Detection (GC-ECD, GC-NPD)
  • Liquid Chromatography : with UV-visible Diode Array Detection (HPLC-DAD, UHPLC-DAD)
