摘要

工作液中溶解气体的含量会影响放气和系统性能。提出了一种用气相色谱法测定烃基液体中氧、氮和二氧化碳溶解气体含量的方法。介绍了采样设备和采样程序。影响气体含量的因素有采样位置、预热时间、液体温度的恒定等。在溶解气体和大气气体之间达到平衡是一个缓慢的过程，需要足够的加热和搅拌。

Measurement of Dissolved Gas Content in a Hydrocarbon-Based Liquid Using Gas Chromatography

The content of dissolved gases in a working liquid can influence outgassing and system properties. A method is presented for determining the dissolved gas content of oxygen, nitrogen, and carbon dioxide in a hydrocarbon-based liquid using gas chromatography. The sampling facility and routine is presented. Various factors influence the gas content such as the sampling position, the preheating time, and the constancy of liquid temperature. Reaching equilibrium between dissolved gases and atmospheric gases is a slow process, requiring sufficient heating and stirring.
