Abstract

PURPOSE:To make the easy detection of sample injection possible by using conductive rubber in the position where the needle of a microsyringe is inserted in the stage of sample injection. CONSTITUTION:When the needle 12 of a microsyringe 10 plunges through conductive rubber 5, an intermediate insulation layer 5a, and further conductive rubber 5' of the lower layer, the 5 and 5' are electrically connected by the conductive needle 12, by which codes 6 and 6' are conducted and an electric signal is obtained. The user injects a sample while pressing a plunger 11. When the plunger 11 contacts the trailing end of the needle upon completion of the injection, the hum of the human body is inputted to a hum detecting circuit 13, and a voltage signal is outputted from a terminal 14; therefore, the completion of the injection of the sample is detected.
