Automated high-resolution gas chromatographic system for recording and evaluation of metabolic profiles.
A fully automated high-resolution gas chromatographic system is described that incorporates repetitive sampling of volatile biological samples onto a glass capillary column, and a simultaneous flame ionization and nitrogen-sensitive detection prior to data acquisition and computer handling. Reliable headspace sampling procedure and reproducible column characteristics that are essential to automation have been studied. The application of this system to the reproducible chromatographic recording of human urinary volatile constituents is shown.
