摘要： The sample device includes a magazine having a rotatable turntable carrying a plurality of circumferentially spaced chambers for receiving sample vessels and movable axially between a sample changing positon and a sampling position. In the sample change position, each sample vessel is pushed against a laterally displaceable closure plate to uncover an aperture in a bottom closure member whereby the sample vessel is receivable in a chamber registered with the aperture. A cradle is carried by the bottom closure member to support the sample vessel as it is displaced through the aperture into the registering chamber. When a selected vessel is aligned with a sampling opening through a closure plate on the opposite side of the turntable, the magazine is displaced axially into the sampling position with the axial displacement causing a needle to pierce the self-sealing diaphragm on the sample vessel. Sampling is effected by pressurizing the vessel and drawing sample components in the vapor phase into the injection block of the gas chromatographic instrument.

摘要： Disclosed is a sample feeding apparatus having a housing defining first and second chambers sealed one from the other and a needle movable longitudinally with respect to the housing. The first and second chambers continuously receive carrier and purging gases respectively through suitable conduits. The needle has an opening normally in communication with the second chamber for continuously purging the needle. Upon application of a sample vessel to a member telescopically received about the housing, the needle is displaced through a seal into the first chamber. Carrier gas is thus provided through the needle into the head space of a sample vessel and the sample will flow to the injection block of a gas chromatograph in response to pressure compensation between the injection block and head space. Upon withdrawal of the sample vessel from below the sampling apparatus, the needle is spring returned to its initial position preventing carrier gas from flowing from the first chamber through the needle.
