      J. Chromatogr. A 1594, 181-189 (2019). Development of a simple and rapid procedure for the determination of quinalphos in human whole blood by HPTLC on silica gel with n-hexane – acetone 9:1 after extraction from spiked blood samples with the optimum solvent, diethyl ether, at pH 3 (average recovery = 93.6%), detection and quantification by densitometry at 325 nm in absorbance mode. Validation by examination of the effect of different organic solvents and pH on the extraction yield of quinalphos, and by investigation of the interference of other organophosphorus pesticides of forensic relevance (not observed). The linearity was in the range of 1 to 100 μg/mL with r2 = 0.9981, the sensitivity (LLOQ) at 1 μg/mL. The within-day precision and between-day precision ranged from 0.2 to 1.0%, and 0.1 to 0.8%, respectively, with an overall average recovery of 91.1% at three concentrations 1, 10, and 50 μg/mL. For different storage conditions for the samples no significant decrease in the concentration of quinalphos was observed. Application of developed procedure in three fatal cases of poisoning.
