Explanation:

HSGC makes use of the equilibrium between the volatile components of a liquid or solid sample and the surrounding gas phase in a sealed vessel, aliquots of the gas phase being injected into GC for analysis. According to the principle of headspace GC, the sample containing volatile components is placed in a sealed vial and conditioned until the volatile components partition into the vapor space above the sample and reach equilibrium; as a result their concentration in the vapor phase is a function of the concentration in the original mixture.

In this method the sample is extracted by inert carrier gas with subsequent GC analysis.

La apropiada selección del gas portador y de sus valores operacionales son esenciales para obtener los mejores tiempos de análisis, mayor eficiencia y reproducibilidad. La velocidad lineal o la rata de flujo del gas portador se controla ajustando la presión del gas portador en el frente de la columna (llamado comúnmente presión de cabeza de columna).
