摘要
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 characteristics of Porpak QS stationary phase are studied. The determination method of polar constant (Mcreynolds consatnt) at 170cccccccccccc coloumn temperature, the thermogravimetric analysis curve and the relative retention values of 17 kinds of of substances are determined. The relationship between coloumn temperature and relation time is studied.
