| Abstract: | A high performance liquid chromatography tandem mass spectrometric method was developed for the simultaneous determination of nine carbamates in wheat samples.Samples were extracted with acetonitrile and cleaned up with neutral-alumina column.,and then determined by HPLC-ESI(+)-MS/MS.In this study,special attention was given to the stability of the system and the matrix effects frequently observed in the ESI(+) process.Proper apporaches dealing with those problems were critically studied.It demonstrated that this multiresidue analysis method is easy,fast,and can meet the requirements for determination of real samples. |
