How to Measure pH in Protein-Containing Samples

Measuring pH in protein-containing samples can be challenging. In order to obtain accurate pH readings, the pH sensor must be maintained in optimal condition.

pH Measurement Basics

Measuring pH in protein-containing samples can be challenging as protein can foul both the pH sensing glass and classical ceramic junctions of the pH sensor. In order to obtain accurate pH readings, both of those compo­nents must be maintained in optimal condition.
