本文研究了低压气相色谱固定相新戊二醇己二酸聚酯 ( NPGA)薄涂柱的热力学特性 ,测定了最佳色谱条件下的溶解焓 ( ΔH)、比保留体积 ( Vg)、气化热 ( ΔHS) ,并与常压色谱柱进行了比较。应用于污水样品分离 ,效果良好
In this paper, the thermodynamic properties of neopentyl glycol adipic acid polyester (NPGA) thin-coated column were studied. The enthalpy of fusion (ΔH) under the best chromatographic conditions was measured, which was lower than the retention volume (Vg), heat of vaporization ΔHS) and compared with atmospheric columns. Applied to the separation of sewage samples, the effect is good
