Analysis of Static Headspace Technique for Partially Volatile Matrices
T.K. Poddar

A theoretical analysis of static headspace gas chromatography for partially volatile matrices has been developed. The existing headspace theory in the literature can be applied to the sample matrices that are nonvolatile in nature. This theoretical analysis has been modified here so that it can be applied to volatile matrices as well. A factor (f) is introduced to account for partial evaporation of the matrix. This matrix evaporation factor can be calculated from the vapor pressure, density, and molecular weight of the matrix. Though the effect of matrix evaporation is insignificant for most aqueous samples, it could be appreciable for various organic matrices having relatively higher molecular weight or vapor pressure than water.
