采用高效液相色谱法,使用C 18柱和紫外检测器,以甲醇+水+磷酸(体积比35∶65∶0.026,pH=2.85)为流动相,在231 nm波长下,对4-甲基-2-肼基苯并噻唑进行外标法定量测定。方法的线性相关系数为0.9992,标准偏差为0.15,变异系数为0.16%,平均回收率为98.3%。
採用高效液相色譜法,使用C 18柱和紫外檢測器,以甲醇+水+燐痠(體積比35∶65∶0.026,pH=2.85)為流動相,在231 nm波長下,對4-甲基-2-肼基苯併噻唑進行外標法定量測定。方法的線性相關繫數為0.9992,標準偏差為0.15,變異繫數為0.16%,平均迴收率為98.3%。
채용고효액상색보법,사용C 18주화자외검측기,이갑순+수+린산(체적비35∶65∶0.026,pH=2.85)위류동상,재231 nm파장하,대4-갑기-2-정기분병새서진행외표법정량측정。방법적선성상관계수위0.9992,표준편차위0.15,변이계수위0.16%,평균회수솔위98.3%。
A method was described for quantitative analysis of 2-hydrazino-4-methyl-1,3-benzothiazole by HPLC using methanol, water and phosphoric acid (volume ratio of 35︰65︰0.026, pH=2.85) as mobile phase, C 18 column and UV detector at 231. The results showed that the linear correlation coefficient of the method was 0.999 2, the standard deviation was 0.15, the variation coefficient was 0.16%, and the average recovery was 98.3%.
