METHOD FOR DETERMINING RESIDUES IN PLASTICS

摘要

The present invention relates to a method for determining dangerous or pesticidal residues in plastics, which comprises processing a plastic sample to a fine powder, converting the powder into a form accessible for determining the analyte, and determining the analyte. The present invention is thus concerned with the analysis of plastics, in particular trace analysis of residues in plastics. The method advantageously allows the use of microextraction techniques and thus a high sample throughput. The method is especially useful for determining whether or not a plastic sample such as agricultural waste plastics contain pesticidal residues.
