A simplified photometric method for the determination of citric acid in biological fluids.
Studies on the oxidation and bromination of citric acid to pentabromoacetone were reported as early as 1847 by Cahours (1). This reaction has since formed bhe basis for many of the procedures for determining citric acid. A qualitative test by Stahre (2), reported in 1897, was adapted fol quantitative analysis by Kunz (3). Pucher, Sherman, and Vickery (4) described the first microphotometric met...
متن کاملThe Micro-Determination of Gold in Biological Fluids and Tissues.
The increasing interest in the use of gold salts as chemotherapeutic agents in the treatment of certain diseases (Hartfall, et al., 1937) has made apparent the necessity of an accurate, specific, and sensitive method for the determination of gold in various biological materials. Moreover, the lack of information regarding the metabolism and pharmacology of this element further emphasizes this n...
متن کاملMicromethod for the determination of uric acid in biological fluids.
A micro procedure for estimating uric acid in body fluids, based on the carbonate method, is described. Interferences are elucidated. The stoichiometry of the reaction is carefully worked out. Reliability of the method is established by comparison with two other methods, by recovery experiments, and by replicate analyses.
متن کاملCitric Acid Determination
Three types of methods have been proposed for the determination of citric acid in urine. Salant and Wise (1) used the unspecific mercuric sulfate reagent of Deniges (2) in a study of the toxicity of citrates. Thunberg (3) developed an enzymatic method employing a dehydrogenase said to be specific for citrate. The remaining methods depend on the so called pentabromoacetone method of Stahre (4), ...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
