Abstract

A glass capillary tube 1 is high-vacuum sealed by means of a valve flange 2 and a cellar 3 of synthetic plastic material to a valve casing 4 having a cylindrical hole 5 in such manner that the lower orifice of the glass capillary interchangeably fits the cylindrical hole 5 of said valve casing. The resilient diaphragm 6 is stretched and fixed to the valve casing by a flange 7 and its middle portion is pressed on the lower orifice of the glass capillary by knurled screw 8 which will close or open said orifice at will. Fig. 2, <PICT:0873928/III/1> not shown, illustrates further embodiment of a sample introduction system according to the invention in detail. During normal use of the sample introduction system the apparatus, as described above, is fitted to the inlet system of the mass spectrometer by means of a flange 10. The capillary section remains closed. The system is now evacuated by aid of a pump. A glass pipette containing a determined quantity of the sample to be analyzed is then placed on the upper orifice 13 of the glass capillary section whereupon the lower orifice 14 of the capillary section is opened by turning the knurled screw in a counter-clockwise direction. Due to the fact that the system is under vacuum the liquid is sucked into the capillary section. As soon as the capillary section is filled, the glass pipette is removed. When the liquid level has reached one of the upper markings 11, the lower orifice 14 of the capillary section is closed. Now the cavity 5 is evacuated again, the vacuum pump is then stopped and the inlet system is now connected via a valve to the inlet system of the spectrometer. By turning the knurled screw 8 the capillary is opened again, the fluid is sucked into the lower portion of the capillary and evaporates at the inner walls of the cavity, due to the fact that the casing is normally heated up by aid of heating members clamped to the outside of the cavity. When the liquid level has reached one of the lower markings 11, the capillary is closed again.
