A highly reliable method of measuring an analyte in a sample using a redox reaction. In this method, a tetrazolium compound is added to a sample prior to the redox reaction so as to eliminate the influence of any reducing substance in the sample, then a reducing substance or an oxidizing substance derived from the analyte is formed, the quantity of the formed substance derived from the analyte is measured by the redox reaction, and the quantity of the analyte is determined from the quantity of the formed substance derived from the analyte. As the tetrazolium compound, for example, 2-(4-iodophenyl)-3-(2,4-dinitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium salt can be used.
一种利用氧化还原反应测量样品中分析物的高度可靠的方法。在这种方法中,在氧化还原反应之前向样品中加入四唑化合物,以消除样品中任何还原性物质的影响,然后形成由被分析物衍生的还原性物质或氧化性物质,通过氧化还原反应测量由被分析物衍生的已形成物质的数量,并根据由被分析物衍生的已形成物质的数量确定被分析物的数量。例如,可以使用 2-(4-碘苯基)-3-(2,4-二硝基苯基)-5-(2,4-二磺酸苯基)-2H-四唑鎓盐作为四唑化合物。
