Using MonoTrap RCC18 (with activated carbon), a simple enrichment and analysis was made for the flavor components of Baijiu (Chinese liquor). It was also possible to collect aroma compounds from a high-matrix sample with an alcohol content of 40%. Agitation and collection, in which the sample comes into direct contact with the MonoTrap, is particularly useful for collecting components with high-boiling points. Plasticizer was found (peaks #27,28) presumably derived from the plastic cap due to stirring or agitation.
