Colorimetric Determination of the Hydrogen Ion Concentration in Small Quantities of Solution.*
The hydrogen ion concentration (1) of many solutions and of culture media is readily determined by means of buffer solutions and suitable indicators. The usual procedure, in determining calorimetrically the hydrogen ion concentration, requires a considerable volume of solution. Frequently the quantity of solution available in experiments upon plants or animals is extremely limited in amount. It...
متن کاملThe Colorimetric Estimation of the Hydrogen Ion Concentration of Blood.*
With the introduction of Cullen’s calorimetric method (1) of estimating the hydrogen ion concentration of blood serum or plasma, it seemed possible for every laboratoryto have a methodemploying minimum material and apparatus and yet secure reliable results. It is generally conceded that the results obtained by the method on normal human plasma or serum agree very well with the true pH as determ...
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...
15 صفحه اولA Colorimetric Method for Determining the Hydrogen Ion Concentration of Small Amounts of Fluid
The importance of the maintenance of the state of neutrality in practically all vital phenomena has become well recognized through the efforts of Sijrensen (l), Michaelis and his collaborators (2), Henderson (3), Clark (4), and nutierous others. The methods devised by them require the use of a considerable amount of fluid. While this fact is not a disadvantage in most types of investigation in ...
