Method and system for preparing samples for gas chromatography

A system for preparing sample material for gas chromatography, the system comprising:

• a. a liquid chromatograph comprising a detector configured for recognizing a chromatographic region of interest in the sample material, the liquid chromatograph having an outlet for the sample material;
• b. a flow-through cuvette having a bore and connecting to the outlet of the liquid chromatograph for providing a stream of sample material flowing therethrough, the cuvette configured to receive a syringe in a gas tight manner;
• c. an insertion device comprising a frame, a syringe and a mount supporting said syringe, the insertion device powered for insertion into the cuvette;
• d. a draw-up device connecting to the syringe for drawing up sample material by the syringe;
• and
• e. a control system connected to the detector and configured for monitoring the chromatographic region of interest, the control system further connected to the insertion device and the draw-up device for controlling the insertion of the syringe into the cuvette and the draw-up of the sample material in accordance with the monitoring of the chromatographic region of interest.
