Objective: To establish a method for determination of the trace elements in yolk lecithin.Method:the samples were digested by closed vesselmicrowave system and analyzed using In as an internal standard by ICP-MS. Results:the linearities were good(r>0.999),the precision of the method were good(RSD<5%,n=6).and the elements recoveries were 92.9%-108.2%.Conclusion: this method is sensitivity and accuracy. It is a feasible method for yolk lecithin.
