| Abstract: | The dependence of the relative intensity of cationic molecule and fragmentation ion of an acetylated melezitose on the concentration of Na + or Li + in the matrix was studied by using fast atom bombardment source.It implies that the mass spectrum with complete structural information can be observed in a proper range of the concentration of Na + or Li +. |

| Keywords: | fast atom bombardment source acetylated melezitose mass spectral fragmentation |
