CHART FOR THE CONVERSION OF COLORIMETRIC READINGS INTO HYDROGEN ION CONCENTRATION

A Colour Chart for the Determination of Hydrogen-Ion Concentration

The 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...

A 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 ...
