Determination of Free Amino Acids by Titra- Tion of the Carbon Dioxide Formed in the Reaction with Ninhydrin
In the present method the CO2 evolved by decarboxylating amino acids with ninhydrin is transferred to standard barium hydroxide and titrated. The conditions for making the ninhydrin reaction quantitative are those previously worked out for applicat,ion in the manometric method (6, 7). The transfer of the CO, to the barium hydroxide is done by a distillation in vacua which is completed in 2 to 3...

determination 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...
15 صفحه اولEstimation of Alpha-amino Nitrogen in Plasma and Urine by the Colorimetric Ninhydrin Reaction.
Methods are described for the estimation of plasma and urine alpha-amino nitrogen by the colorimetric ninhydrin reaction; in the method for urine, both ammonia and urea are separated by a rapid ion-exchange resin procedure. Two methods of estimation are given; one has the advantage of great simplicity, but involves the use of cyanide; in the other, cyanide is eliminated. Normal values are repor...
