Abstract
In the sample introducer system disclosed herein, a sample-carrying probe engages and releases, from a sample-introducing port, a plug which closes the port when the probe is not in place. The probe then carries the plug ahead of itself into an evacuated chamber where the sample may be analyzed. Upon withdrawal of the probe, the plug is replaced so as to seal the port.
