针对国外Porapak QS的色谱性能进行了研究,测定了极性常数(麦氏常数),提出在柱温170℃测定其常数的方法,测定了热分析曲线和17种物质的相对保留值;对柱温与保留值、关系进行了研究。
The chromatographic properties of Porapak QS abroad were studied. The polar constants (the Macbeth constants) of the Porapak QS were determined. The method of determining the constant at 170 ℃ was proposed. The thermal retention curves and the relative retention values of 17 materials were determined. The relationship between temperature and retention was studied.
