Abstract: An apparatus for connecting the end of a tubular body, particularly a chromatographic capillary tube, to a detection or injection device fitting including a holder having a ferrule for holding the tubular member and an insertion assembly to engage the device fitting. The assembly is adapted to contain the holder and force the ferrule into a seated relation with the device fitting. A method for connecting a tubular member to a device fitting is also provided.

Abstract: To inject samples into a mass spectrometer, one end of a capillary tube is affixed directly to the vacuum chamber of the mass spectrometer or to a mass spectrometer interface to bring gaseous samples into close proximity to the mass spectrometer ionizing means, and the other end is in close proximity to the surface of a tape. The tape is in a cassette and a probe is inserted through the cassette frame between the cassette reels and draws the tape to the end of a capillary tube. Regions of tape with samples adsorbed to tape surface are transported rapidly from a low temperature region for a high temperature region which includes the entrance end of the capillary tube. Sample vaporizes from the tape surface and is carried into the capillary tube by a carrier gas. The tape position is indicated by bar codes on the tape that control tape movement.
