A method was developed to separate, detect and qualify aldicarb, bendiocarb, carbaryl, carbofuran, ethiofencarb, methomyl, methiocarb, propoxur in meats and fruits. Experimental beef and fork samples were fortified with 0.05mg/kg of carbamate pesticides for analysis. Carbamate-detected pear by HPLC fluorescence detector(HPLC/FLS) are extracted with acetonitril and refined by solid phase extraction(SPE) filled with aminopropyl-bonded silca, In the following step, the injected materials into LC/MS are analyzed to result in the fact that bendiocarb, carbaryl, carbofuran, ethiofencarb, methomyl, methiocarb, propoxur presents several sorts of fraction ions following with; [M+H]+, [M+Na]+, [M-CONHCH3]+, [M-OCONHCH3]+. In addition, ethiofencarb presents [M-SCH2CH3] ion distinctive and aldicarb presents [M+Na]+ and [M-OCONHCH3]+ ion which is the most decisive fraction ion for pesticides such as bendiocarb, carbaryl, carbofuran, ethiofencarb, methiocarb, methomyl, propoxur excluding [M+H]+ ion. However, [M-OCONHCH3]+ and [M-OCONHCH3]+ fraction ion charactering carbamate pesticides are detected most efficiently with fragment voltage 50eV. As a result, for quantitative analysis, [M+Na]+ ion is the most decisive ion for detection of aldicarb and [M+H]+ ion is the most decisive fraction ion for pesticides such as bendiocarb, carbaryl, carbofuran, ethiofencarb, methiocarb, methomyl, propoxur. Carbaryl-detected pear by HPLC/FLS are analyzed by LC/MS and the result shows that [M+H]+ and [M-CONHCH3]+ ions charactering carbaryl are detected.
