| Abstract: | This thesis developed a LC-MS-MS method for rhodamine B in oil chili.The mass spectrometer was operated in the positive ion mode using multiple reaction monitoring.In the method,A sample was extracted with acetonitrile,Chromatographic separation was carried out on a Waters-C18 column(2.1×50 mm,1.7 μm)using methyl alcohol and water(containing 0.01%(v/v) formic acid).The limit of detection is 0.1ng/mL,the linear plots were 0.05 μg/L-10 μg/L.Overall recoveries were 99.5%~106.4%,and RSD value was 1.08%~3.07%. |
