ABSTRACT:
A method of transferring and injecting a liquid sample, by supplying an inert gas to an injection needle after normal injection has taken place by the action of a plunger. The injection syringe is constructed to allow the inert gas to pass freely even when the needle is fully depressed, to remove any drop clinging to the tip or needle inner wall.
