DIAZO REAGENT FOR MEASURING BILIRUBIN

摘要

PURPOSE:To enhance the stability of a measuring reagent without changing the fundamental composition thereof and to eliminate preparation trouble at the time of use, by allowing alkali halide to coexist along with diazonium salt formed through the reaction of sodium nitrite and sulfanilic acid. CONSTITUTION:Alkali halide such as sodium chloride is allowed to coexist along with diazonium salt formed through the reaction of sulfanilic acid and sodium nitrite as a stabilizer in an amount 10-20 times that of diazonium salt in a mol ratio.
