Study of some alcohol amounts in commercial alcoholic disinfectant solutions using gas chromatography with flame ionization detection

A simple solvent extraction method was used to analyze alcohol-based hand rubs (ABHRs) using gas chromatography with a flame ionization detector. 79 samples including 68 liquid and 11-gelled ABHRs were analyzed in the Food Drug Laboratories Research Center of Mashhad, Iran. 17 had methanol, 50 correct percentage alcohol (60-80%), 12 incorrect (<60%). The RSD% ethanol, isopropanol as 2.28, 2.18, 1.52, respectively. relative recoveries for 102.5, 97.8, 114, All experiments repeated three times. limit detection quantification obtained 0.22, 0.24, 0.10 (%) 0.71, 0.82, 0.68 (%),
