Multi-residue-analysis of pesticides by HPLC after solid phase extraction

Summary HPLC is a good method for analyzing a broad variety of different pesticides in drinking and surface water. Due to a high enrichment factor in solid phase extraction and the sensitive detection in the UV-range many pesticides can be determined even at a concentration lower than 0.05 g/l. By the use of a diode-array-detector a good security is reached for the identification of substances.
