Abstract: To detect trace elements such as Cu,Pb,Cd in candy with ICP-MAS is studied. Using internal standard addition and XI interface, the impacts on matrix effect, interface effect and mass spectrum interference will be eliminated efficiently. The results of detection limit, recoveries for spiking sample and relative standard deviation are perfect enough to meet the target.

Key words: candy, heavy metal elements, interference, ICP-MAS(inductively coupled plasma-mass spectrometry)
