| Abstract: | A method of isotope dilution inductively coupled plasma mass spectrometry for the determination of selenium in IMEP-17 serum samples is established. The serum selenium was prepared by using microwave digestion andsulphydryl cotton separation. This method of sample preparation can efficiently eleminate matrix interference. The results obtained agree well with the certified values. |
