LPGC/MS is the most practical and beneficial fast-GC technique available to achieve 10 min analyses in applications that typically take 30 min. Sample capacity and column robustness are increased greatly using LPGC to permit large-volume injection with standard inlets without column maintenance, and, because vacuum conditions generate taller and narrower peaks that are still suitable for standard MS data acquisition rates, sensitivity
is also increased. Enhanced selectivity of detection using modern MS tools and software compensate for reduced chromatographic peak capacity. In our view, LPGC/MS should be the first option for evaluation in many
GC/MS applications to provide fast, sensitive, and robust analyses.
