【摘要】 报导了色谱仪监测氩气中有机蒸汽(苯、丙酮、三乙胺)浓度的方法。利用标准量的液体进样建立样品量-色谱峰高的定量曲线。测量多级雪崩室工作气体的色谱峰高,与定量曲线比较求得其中有机蒸汽的浓度。测量结果表明,利用一个简单的气体混合系统,可获得浓度稳定性很高的多级雪崩室混合气体。更多还原

【Abstract】 We have reported a method of monitoring the concentration of organic vapour inMSC by chromatography. Using standard samples of liquid, the standard curves ofsamples-chromatogram peaks are established. Then the chromatogram peak height inthe worked gas of MSC are measured, and the concentration of organic vapour isobtained by means of comparison with the standard curves. The measurements showthat using a simple gas mixing system a very high stablity of the concentration of themixture gas in MSC may be obtained.更多还原
