Role of the solid carrier in the analysis of impurities
The solid carrier used for analyzing impurities in nonpolar liquid phases has a marked effect on the quantitative analyses. For a quantitative verification of the method, we recommend special analyses of artificial mixtures, the composition of which are close to that of the mixture being analyzed.
In the case of gas-liquid chromatography, when nonpolar liquid phases are used the analysis of impurities should be performed on inert carriers or on carriers modified with small amounts of polar substances.
