| 摘 要： | 采用离子色谱柱切换技术同时测定了保留性质差别较大的有机酸以及不同价态的无机阴离子。由于柱切换基本不影响色谱基线,该法有较高的灵敏度。同时测定了食品中的乙酸,山梨酸、苯甲酸、糖精、氯离子和磷酸根。

| Abstract: | Column-switch ion chromatography was adopted in developing a method for simultaneousdetermination of multicomponents in food. Because of the chromatographic base line do notinfluenced by switch of column, therefore a higher sensitivity may be achieved by this method.Food sample containing acetic acid, sorbic acid, saccharine, Cl~-, and PO_4~(3-) has been determinedsimultaniously by this technique. Experimental conditions are given. |
