摘　　要：由于便携式GC-MS具有体积小、操作简单、便于现场快速测定,而在突发应急事件中广泛应用,但是在标准曲线测定时,苏马罐与便携GC-MS直接相连进行分析,其分析结果准确度低且平行性差。为此,设计了一个三通阀,在进行气体的采集分析时,准确度高且平行性好。Because the portable GC-MS has a small size and simple operation,it is convenient for rapid on-site measurement and is widely used in emergencies.However,when measuring the standard curve,the Suma tank is directly connected to the portable GC-MS for analysis.The result is low in accuracy and poor in parallelism.Therefore,a three-way valve is designed in this paper to collect and analyze gas with high accuracy and good parallelism.

关 键 词：GC-MS三通阀 平行性 准确度
