Automated Simultaneous Determinations of Titratable Acidity and Ammonium Ion in Urine

Le résumé fourni par la source

A manifold for simultaneous determination, by automated continuous-flow analysis, of ammonium ion and titratable acidity of small volumes of urine is described. The total amount of sample necessary is less than 0.5 ml. Reagents of existing methods are modified and typical recorder tracings are shown to demonstrate reproducibility. Comparison of the commonly used manual method for titratable acidity and the automated method described showed tolerable limits of error between them, indicating that the performance of the latter method was acceptable. Recoveries for both ammonium and titratable acidity were in the acceptable ranges.
