| Abstract: | To develop a method for analyzing 10 amides in fruits ang vegetables by Liquid chromatography-spectrometer.The sample was extracted with acetonitrile,cleaned with solid phase extraction,separated with LC,and determined by MS/SIM/APCI.The calibration curves of standard solutions was linear in the range of 0.05 mg/L-5 mg/L for 10 amides,the relative coefficient was over 0.995 6,the average recoveries for 10 analytes was ranged from 72.8 % to 96.6 %,precisions was under 11.1 %,with limits of detection was 0.01... |
