AbstractAn HPTLC method for determining fluorimetrically the residues of coumaphos in honey samples is described. The active ingredient is solid phase extracted with a C‐18 disposable column and determined densitometrically on HPTLC pre‐coated silica plates. The method does not require additional clean‐up steps, is extremely quick and can easily be adapted to routine determinations of a large number of samples. The determination limit is 0‐01 mg kg−1and recoveries are
