Measurement of the pH adjacent to membrane surfaces is often complicated by electrostatic charge and solvation effects on the pKa of surface-bound indicators. The pKa of membrane-intercalated fluorescein DHPE (F362) is ~6.2, quite close to that of free fluorescein. Researchers have used ...
pH analyzers from METTLER TOLEDO are in-line pH meters for ensuring accurate, continuous pH measurement in a broad range of industrial and hygienic processes. These pH analyzers provide accurate measurement in pharmaceutical manufacturing, chemical produ
The pH value is used as a unit of measurement for the acidity or alkalinity of a liquid medium. The pH-sensitive element of glass electrodes is a glass bulb that supplies an electrochemical potential which is dependent upon the pH value of the medium. This potential is generated bec...
The first buffer solution shall be chosen so that the pH-value of the buffer solution is in the same region as the electric zero point of the pH-meter (usually = 7). The reading for the second buffer solution should agree with its correct value to within 0,1 pH-unit. If the pH-...
Combine measurement of the pH value with temperature: pH measurement in aggressive media: pH measurement – good to know: The pH value is an important indicator in numerous chemical and biochemical reactions and stands for "pondus hydrogenii" - hydrogen weight. Why?
