本文自行设计安装一套以减压法采样的液上采样装置,选择出在与气相色谱仪配套使用中的合适操作条件。并用两组文献中的气-液平衡数据检验了自制液上采样系统的可靠性。讨论了用液上气相色谱法测定溶液平衡总压的可行性。
In this paper, we design and install a set of vacuum sampling method on the liquid sampling device, select the gas chromatograph supporting the use of the appropriate operating conditions. The reliability of self-made liquid up-sampling system was tested with gas-liquid equilibrium data from two groups of literature. The feasibility of determining the total solution equilibrium pressure by liquid chromatography was discussed.
