Abstract

1,269,498. Sampling valve for gas chromatography. PERKIN-ELMER Ltd. 16 April, 1969 [26 April, 1968], No. 19831/68. Heading B1X. [Also in Division F2] A sampling valve for gas chromatography has six ports such as 10 opening into the floor of a circular groove 1C formed in the upper face of block 1B. Overlying the face is a diaphragm 4 which has spaced portions thereof pressed into the groove by three balls such as 8 subjected to a spring load 11 via balls 13 and washer 15. Balls 8 are carried by a cage 9 rotatable via screw 10A by knob 10 threaded on diaphragm clamp ring 6. The groove may alternatively be defined wholly or partly in the diaphragm. In use, balls 8 in one position are located between selected adjacent pairs of ports such that a carrier gas flows in one port and out another, whilst a sample gas flows in one port, out to a sample loop, back in from the loop and then out of another port. Upon rotation of knob 10, balls 8 are eventually repositioned to divert the carrier gas through the sample loop instead of the sample gas. In Fig. 4, six non-rotatable balls 25 are used and are depressed in two groups of three, to connect the ports as above, by face cam 28 which transmits an adjustable load from spring stack 29 and bearing 31 to balls 25 via balls 27 and tappets. A vacuum may be applied at 41 to assist unseating of the diaphragm; springs may also be used. The diaphragm can be of glass-fibre filled silicone rubber with a p.t.f.e. facing, or of nylon-reinforced nitrile rubber.
