摘要：
An apparatus (10) for introducing gaseous samples from a wide range of environmental matrices into a mass spectrometer (14) for analysis of the samples is described. Several sample preparing modules (30) including a real-time air monitoring module (94), a soil/liquid purge module (136), and a thermal desorption module (162) are individually and rapidly attachable to the sample introducing apparatus (10) for supplying gaseous samples to the mass spectrometer (14). The sample-introducing apparatus (14) uses a capillary column (24) for conveying the gaseous samples into the mass spectrometer (14) and is provided with an open/split interface (32) in communication with the capillary (24) and a sample archiving port (70) through which at least about 90 percent of the gaseous sample in a mixture with an inert gas that was introduced into the sample introducing apparatus (10) is separated from a minor portion of the mixture entering the capillary (24) discharged from the sample introducing apparatus (10).
