FIELD: analytic chemistry. SUBSTANCE: determination of microquantities of sormamide is carried out on standard plates with thin layer of sorbents secured with starch in mobile phase consisting of mixture of carbon tetrachloride and acetone in volume ratio of (20-15):1 with subsequent detection of zone of localization of tested substance by treatment of chromatograms with Dragendorf's reagent modified with 0.2% aqueous solution of ascorbic acid. EFFECT: higher efficiency.
