How do I measure the pH of creams, emulsions? Are the measurements easy?
Yes, the measurements are easy, when you use an electrode with a sleeve or ground glass joint diaphragm for the reference.
Electrodes need special care in samples containing detergents (surfactants). For details please check with pHil…
For
routine measurement the new 827 pH lab with Metrosensor
Viscotrode (ground joint diaphragm) is first
choice.
Your system without worries includes the Metrohm
model 780 pH Meter and a Metrosensor Viscotrode
(ground joint diaphragm).
