ABSTRACT:
A device is disclosed for coordinating the position of an injection syringe needle in a gas chromatographic apparatus with at least one other operation of the gas chromatographic apparatus downstream of the device. The device comprises a first channel for introducing the injection syringe. The first channel is substantially aligned with the injection channel of a gas chromatographic injector. The device also includes a position sensor and a lever rotatable around a lever axis substantially perpendicular to the axis of the first channel, wherein the lever has an arm and a shaped appendix, wherein the shaped appendix protrudes into the first channel when the lever is in its rest position, and wherein the appendix is positioned so that, when an injection syringe is introduced into the channel past said point, the injection syringe contacts said appendix and causes rotation of the lever about the lever axis from its rest position so that the arm acts on the position sensor to indicate detection of the presence of the injection syringe in the first channel at said point. The device further includes at least one servomechanism actuatable in response to the detection of the syringe in the channel for controlling the other operation depending on whether or not the injection syringe is detected in the channel.
