  • Title: Rapid and direct determination of selenium, copper, and zinc in blood plasma by flow injection-inductively coupled plasma-mass spectrometry.
    Author: Kobayashi K, Katsuya Y, Abdulah R, Koyama H.
    Journal: Biol Trace Elem Res; 2007 Jan; 115(1):87-93. PubMed ID: 17406076.
    Abstract:
    A flow injection-inductively coupled plasma-mass spectrometry (FIICP- MS) with a simple sample preparation procedure was developed for the determination of selenium, copper, and zinc in blood serum/plasma. A serum/plasma sample was filtered through a 0.45-mum membrane filter and diluted with a mixture of trace elements in a standard solution (9 : 1, v/v). Measurement of the reference serum sample confirmed the accuracy of our method for selenium, copper, and zinc concentration. In the case of blood plasma samples obtained from six healthy adult males, the selenium, copper, and zinc concentrations were similar to those of a typical healthy male in Japan. These results suggest that the sample preparative procedure coupled with FI-ICP-MS can be used for the routine determination of selenium, copper, and zinc in human blood serum/plasma.
