Headspace Analysis of Aroma Compounds Using Porous Adsorbents

A novel procedure is developed for the quantitative determination of volatile compounds in the vapour phase over samples. Substances were extracted and preconcentrated from the headspace on porous polymer adsorbents under the conditions of thermodynamic equilibrium, followed by back extraction from the adsorbent using organic solvents. The final monitoring was performed by capillary gas chromatography with an internal standard.
