| Abstract: | A method for the determination of many colorant, preservatives and sweeteners simultaneously by high performance liquid chromatography was researched. The effects of liquid componets, liquid amount, buffer concentration, column temperature and flow - rate on the separation and determination were studied. Under the best condition, the correlation coefficient of eight elements were in the range of 0.999 2 - 0.999 9. The added recoveries of samples were in the rage of 97. 6 % - 99.4 %, the method achieves the simultaneous determination of eight elements in 18 minutes. This method is successfuUy used to determine many colors, preservatives and sweeteners with rapidly, accurately and sensitively. |
