[A modified method for the microdetermination of citric acid].
An investigation of the different steps in the method of Weil-Malherbe & Bone (1949), as modified by Taylor (1953), has led to an altered procedure for citric acid determination, with increased sensitivity and accuracy. The main modifications involved are the use of (i) a higher concentration of sulphuric acid during the formation of pentabromoacetone, and (ii) a thiourea-borax-sodium sulphide ...
متن کاملResorcinol Method for Colorimetric Microdetermination of Copper in Pure Forms
A simple colorimetric method is proposed for the micro-determination of copper in pure forms. The assay is based on the formation of a color complex between copper and resorcinol in presence of ammonia with peak absorption at 450 nm. The method is linear over 0.05 through 1.0 μg Cu (R ≥0.99). The regression coefficients vary from 0.275 to 0.920 depending upon the choice of experimental conditio...
متن کاملMethod for rapid infrared microdetermination of serum carbonate.
C ARBON DIOXIDE can be measured by infrared absorptiometry, so carbon dioxide evolved from a sample of serum or plasma by acid can be determined by this instrumental technique. Procedures published earlier based on this approach (1, 2) were not competitive with other techniques available for analysis of blood carbonates since they required 1.0 and 0.5 ml of blood, respectively, for the sample a...
متن کاملThe colorimetric microdetermination of urea nitrogen by the xanthydrol method.
Although many methods for the determination of urea nitrogen have been described, few have proved highly convenient for the accurate determination of small amounts of urea nitrogen without having to make use of special apparatus or techniques. Among the older methods, the Van Slyke gasometric method (1) is generally considered the most accurate, with an allowable error of 1 per cent. This metho...
متن کاملAMPEROMETRIC MICROBIOSENSOR FOR THE DETERMINATION OF CHOLINE
The construction and performance of an amperometric microbiosensor for the determination of choline chloride by immobilizing choline oxidase on a cellulose acetate membrane are described. The procedure of choline determination involved the electrochemical detection of enzymatically generated hydrogen peroxide. This microsensor has a linear response between 0.038-0.1 mM choline chloride. The...
