建立一种同时分析2甲4氯和氯氟吡氧乙酸异辛酯的高效液相色谱法。采用反相高效液相色谱法,以甲醇、水和乙酸为流动相,使用ODS色谱柱和紫外检测器,在220nm波长下对试样中2甲4氯和氯氟吡氧乙酸异辛酯进行液相色谱分离和定量分析。2甲4氯和氯氟吡氧乙酸异辛酯的线性相关系数分别为0.999 1和0.999 0,标准偏差为0.026和0.032,变异系数为0.09%和0.53%,回收率为99.84%和99.63%。方法简便、快速、准确度高,可以满足2甲4氯和氯氟吡氧乙酸异辛酯的定性和定量分析。
A high-performance liquid chromatography (HPLC) method was developed for the simultaneous analysis of 2-MCPD and iso-octyl fluride acetate. Using reversed-phase high-performance liquid chromatography with methanol, water and acetic acid as the mobile phase, using ODS column and UV detector, at a wavelength of 220nm in the sample of 2 A 4 chlorine and clopidogrel acetic acid isooctyl Liquid chromatography separation and quantitative analysis. The linear correlation coefficients of MCPA and isooctyl fluticasone were 0.999 1 and 0.999 0 respectively, the standard deviations were 0.026 and 0.032, the coefficients of variation were 0.09% and 0.53%, and the recoveries were 99.84% and 99.63% respectively. The method is simple, rapid and accurate, and can meet the qualitative and quantitative analysis of MCPA and isooctyl fluride.
