title: [HPTLC for the confirmation of results in the analysis of pesticide residues].
abstract: HPTLC is an effective method for confirming gas-chromatographic results for insecticide and fungicide residues in sample solutions obtained by clean-up of fruit and vegetable extracts according to the Deutsche Forschungsgemeinschaft multiresidue method S 19. This study describes the possible interference caused by co-extractives from some crops rich in typical components, and gives the best operating conditions for separating and detecting the residues by HPTLC on silica gel and C18 reversed-phase material. The routine limit of determination was 0.01-0.05 mg/kg in most cases.
