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.
