Zusammenfassung:An automated gas chromatographic system for making fast-turnaround measurements of alkyl nitrates was developed and tested. Every 30 min, samples were automatically acquired on a 1/16-inch OD Tenax trap made from fused silica-lined stainless steel tubing and injected by thermal desorption into the gas chromatograph. The system exhibited good chromatographic resolution, minimal breakthrough, and on-trap stability for C sub(3)-C sub(5) nitrates. The detection limit of the instrument was
