IMPROVED GAS CHAIN METHODS OF DETERMINING HYDROGEN ION CONCENTRATION IN BLOOD

The Accuracy of the Dale and Evans Method of Determining the Hydrogen Ion Concentration of Blood.

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...

Hydrogen ion concentration changes in mitochondrial membranes.

1. Bromthymol blue added to rat liver mitochondria at concentrations in the range 0.4 to 4.0 mpmoles per mg of protein is tightly bound as indicated by centrifugation and washing of the mitochondria. 2. The absorbance of the dye is increased on adding Ca++ or Mn++ to the mitochondria in the absence of a permeant anion. The extent of increase is 0.03 cm-l for 167 PM Ca++ at 618 rnp for 0.5 mpmol...

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 ...
