ã€Abstractã€‘ 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.æ›´å¤š è¿˜åŽŸ
