Fully-sealed trace water determination system with automatic quantitative sample introduction

The invention relates to a fully-sealed trace water determination system with automatic quantitative sample introduction, comprising a linear motor mounted on a substrate. The handle of a sample-introduction injector is connected with the linear motor, the injection head of the sample-introduction injector is communicated with the left part of a sampling tube through a pipeline, and the right part of the sampling tube is communicated with an electrolytic cell through a pipeline; a heating blower is communicated in series with a drying bottle through a pipeline and communicated with the left top of the sampling tube through a pipeline; a photoelectric switch is arranged at the right part of the sampling tube; an air pump is communicated with a cleaning bottle through a pipeline and communicated with the left part of the sampling tube through a pipeline; and the right top of the sampling tube is communicated with an oil cup through a pipeline. The invention has the advantages that a certain amount of samples ca
