Abstract
<PICT:0855234/III/1> <PICT:0855234/III/2> <PICT:0855234/III/3> <PICT:0855234/III/4> <PICT:0855234/III/5> <PICT:0855234/III/6> <PICT:0855234/III/7> A sampling device for chromatographic-analysis apparatus is connected to inlet and outlet conduits for the sample to be analysed, being also connected to inlet and outlet tubes for the carrier gas and affording a flow path either between said conduits or between said tubes and, by switching from one path to the other, a sample is enclosed and transferred from the test stream to the carrier stream. Fig. 1 illustrates an embodiment of the invention comprising a body assembly having two sections 10 and 11 mounted on a common shaft 12 and movable in relation to each other about the axis of the shaft 12. The internal passages through body member 10 are connected as illustrated in Fig. 1 with a hollow tube 20 which functions as a sample chamber which by welding or other appropriate means can be arranged to be an operative part of the body assembly. The member 11 is provided with a number of arcuate openings 25 (see Fig. 2) and may extend through an angle sufficiently large to include adjacent internal passages. The rotational disposition of member 11 determines which of the adjacent internal passages of member 10 of the body assembly are connected through the openings 25. If the passages are connected as shown in Fig. 3 and are then switched to the connections as in Fig. 2 it can be seen that the amount of fluid from the first stream which was passing through the sample chamber 20 at the instant of such rotation of the assembly is thus introduced into the second fluid stream and becomes the sample. Fig. 4 and 5 illustrate another embodiment of the invention wherein the two sections 40 and 41 of the body assembly are also positioned in contact with each other. Figs. 6 and 7 illustrate yet another embodiment in which the stationary member 51 of the body assembly is composed of two sections 52 and 53 which are made structurally unitary by a plurality of interconnecting pins 54 and a number of sample chambers 60, 61, 62, 63, 64 and 65 are contained in the rotatable member 55.
