摘要： A sample injecting device is provided for reducing carryover. The sample injecting device includes the following mode: a needle is set at a low descending speed when sample is injected into an injection port in a total-volume injection manner by the sample injecting device. When the needle is in contact with the injection port, the needle is set at a low speed, thereby increasing the accuracy of the position of the needle relative to an injection hole and decreasing friction between the needle and the injection hole. Contaminants present in the injection hole are prevented from easily flowing from the injection hole into an analyzing flow path, so as to achieve an excellent low carryover.
