摘要

FIELD: chemistry.;SUBSTANCE: method for determination of compliance of chromatographic peaks, obtained on columns with polar and non-polar phases, to one and the same component of sample consists in the fact that analysed sample is placed into hermetic vessel, exposed at temperature 100°C for 40 minutes; components of equilibrium steam phase are bubbled through small volume of liquid solvent. Then obtained extract and equilibrium steam phase are chromatographed on polar and non-polar columns, and compliance of chromatographic peaks to one and the same component of sample is determined by ratio of obtained concentrations of said component both in analysis of liquid extract and equilibrium steam phase.;EFFECT: increased quantity of determinable volatile components of sample and increased convergence of determination of concentration of sample volatile components.;1 tbl
