FIELD: food-processing industry.
SUBSTANCE: method involves preparing sample of product to be analyzed; introducing the given sample into chromatographic column. Apparatus has chromatographic column comprising at least one sorbent capable of absorbing evaporated mobile phase between liquid mobile phase front and rear front of component under analysis process. Detector is positioned downstream of each sorbent for determining respective component.
EFFECT: increased precision in determining composition of products.
