Soil quality. Determination of organochlorine pesticides by gas chromatography with mass selective detection (GC-MS) and gas chromatography with electron-capture detection (GC-ECD)

BS ISO 23646:2022 发布历史

What is ISO 23646 - Determination of OCPs about?    Organochlorine pesticides (OCPs) are organic synthetic substances that are globally used. ISO 23646 specifies a method for the quantitative determination of OCPs and semi-volatile chlorobenzenes in soil and sediment, using GC-MS and GC-ECD.   Based on the properties of the samples, ISO 23646 contains decision tables regarding drying-, extraction- and clean-up procedures. The method described in ISO 23646  is performance-based. It can be modified if all performance criteria given in this method are met. ISO 23646 applies to the analysis of other chlorinated compounds not specified in the scope in cases where suitability has been proven by proper in-house validation experiments.   Note: The validation data are shown in Annex A. ISO 23646 applies only to α-HCH, β-HCH, γ-HCH, δ-HCH, o,p′-DDE, p,p′-DDE, o,p′-DDD, p,p′-DDD, o,p′-DDT and p,p′-DDT. For sediments, data are displayed and measured using an ECD detection. The comparability of ECD and MS data in terms of the approach of ISO 23646 was demonstrated on additional matrices.
