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

Analysis

• 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 …)

Material

• 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)
