Description
技术领域 technical field
本实用新型涉及一种实验进样注射器推进器，特别涉及一种进样注射器推进器。 The utility model relates to a propeller for an experimental sampling injector, in particular to a propeller for a sampling injector.
背景技术 Background technique
目前，色谱分析仪器需要使用注射器进行进样，将样品进样打入仪器的气化室，汽化并经分离后，再进行色谱分析。进样时速度要求要快，如果注射速度慢时会使样品的汽化过程变长，导致样品进入色谱柱的初始谱带变宽，影响分析。另外，现有的手动进样，手指容易传热到针筒，影响了样品温度，进而影响分析结果。 At present, chromatographic analysis instruments need to use syringes to inject samples, inject samples into the gasification chamber of the instrument, vaporize and separate, and then perform chromatographic analysis. The injection speed is required to be fast. If the injection speed is slow, the vaporization process of the sample will be prolonged, resulting in the broadening of the initial band of the sample entering the chromatographic column, which will affect the analysis. In addition, in the existing manual sample injection, the fingers are easy to transfer heat to the syringe, which affects the sample temperature and further affects the analysis results.
