Abstract

The valve head consists of a cap (3), a guide (2) for a movable plunger (1), and a seal (9) for the gas chromatograph column (6). The cap and guide are screwed together and a grooved spacing disc (4) guides the end of the capillary column, which is vacuum-sealed with graphite (8). The plunger has a conical tip which can form a seal with the upper edge of a cup-shaped recess having a nozzle aperture (7) in its floor. It can reciprocate up to 20 times per second, solenoid-driven with opening times between 100 and 200 microns.
