Abstract
A micro-scale sample introduction control system comprises a base plate, a sample introduction mechanism and a syringe both arranged on the base plate. The sample introduction mechanism is driven by a stepping motor. The output shaft of the stepping motor is connected with a leading screw. A leading screw nut on the leading screw is connected with a push block through a connecting support. The push block is connected with the syringe through a push rod. The syringe is arranged on the base plate through an upper syringe support plate and a lower syringe support plate arranged on the two ends of the syringe. A slide rail is arranged on the base plate. The slide rail is connected with the connecting support. The stepping motor is controlled by a motor drive plate. The motor drive plate is electrically connected with an optical coupler arranged on the base plate. The leading screw and the stepping motor are connected through a shaft coupling. The optical coupler is arranged below the shaft coupling. An optical coupler separation blade is arranged on the connecting support. The micro-scale sample introduction control system has the advantages of reasonable structure, accurate mechanism control, sample addition precision, small gap, good repeatability, high efficiency, simple installation and simple maintenance. The system can precisely control the sample amount.
