Abstract

A standard direct introduction capillary interface is used for the SFC‐MS analysis of polymer additives. The system is optimized with respect to the position of the restrictor, probe tip temperature, and ion source temperature. El‐like charge‐exchange spectra are obtained. Cl using ammonia as the reagent gas is used for the quantitative analysis of a real world sample.

The experimental capillary SFC‐MS spectra obtained show a good similarity with those recorded using the direct insertion probe. The influence of the experimental conditions on the mass spectra obtained is evaluated statistically.
