PURPOSE:To inject a thermally unstable sample stably and reproducibly by using a pulse motor in the suction (injection) mechanism and by making the device perform a multistage suction. CONSTITUTION:The pulse motor 10 is used to move the piston of microcylinder 1, the up-and-down movement of the piston is performed by the pulse generator 11. When the pulse motor turns through an angle of 1.8 degrees every one pulse count, it rotates one time every 200 pulses. Since the quantity of suction is controlled by the pulse counts, the multistage suction of a sample can be performed. |
