Modified capillary GC/MS system enabling dynamic headspace sampling with on‐line cryofocusing and cold on‐column injection of liquid samples

Abstract

Abstract The paper describes a capillary GC/MS hardware arrangement allowong either: on‐line injection of sample of gases and vapors coming from dynamic headspace or purg & trap samplers and their subsequent cryofocusing/thermal desorption prior to the analytical capillary column (first column): direct injection of liquid samples through a cold on‐column injector into a second analytical column (counted in series with the first). Chromatographic profiles of acacia honey aromas provide condirmation of the suitability of this system.
