Fourteen analysts from 9 laboratories evaluated a high pressure liquid chromatographic procedure for the determination of 4,4'-(diazoamino)-dibenzenesulfonic acid (DAADBSA) in FD&C Yellow No. 6. Each collaborator analyzed 5 samples nominally containing 0-0.050% DAADBSA. The repeatability and reproducibility of the method are estimated to be 0.003% and 0.020%, respectively. The method has been adopted as offical fist action.
来自9个实验室的14名分析人员对一种用于测定FD&C黄6号中4,4'-(重氮氨基)二苯磺酸(DAADBSA)的高压液相色谱法进行了评估。每位协作人员分析了5个标称含有0-0.050% DAADBSA的样品。该方法的重复性和再现性估计分别为0.003%和0.020%。该方法已被采用为官方首次行动方法。
