ABSTRACT:
A sample charger for a gas chromatograph has a charging chamber constructed for connection to the separating column of the gas chromatograph and receives a sample container in the form of a tube by the lengthwise insertion of a rod-shaped sample holder which comprises a hollow insertion tube, in which the sample container is releasably secured at its forward end. The charging chamber and insertion tube have carrier-gas inlet openings so that the interior of the insertion tube and the sample container can be scavenged with inert gas during the insertion process and, after the sample container has been completely inserted into the charging chamber, the carrier gas flows through the container into the separating column.
