  • Method of measuring metals in samples of living body
    Patent number: 5925570
    Abstract: A method and a reagent for highly accurate measuring of trace amount of metals in a sample of living body. The method and the reagent for measuring metals in a sample of living body includes:(1) a method for measuring metals in sample of living body, in which metals other than the objective metals of measurement are added to the measurement system to release the objective metals bonding to co-existing substances in the sample from the co-existing substances; and(2) a reagent for the measurement, in which metals other than the objective metals of the measurement are contained in a reagent for measuring metals in a sample of living body in order to release the objective metals bonding to the co-existing substances in the sample from the co-existing substances.
