for Colloidal Titration

Colloidal titration is used in various fields as a simple quantitative method for polymer electrolytes. This reaction utilizes the phenomenon in which the polymer cations and polymer anions associate together.
At the endpoint of titration, an indicator (toluidine blue; TB) is added to react with polyvinyl sulfate (PVS), and judgment is performed through the change of color from blue to red-purple.
The reagents for colloidal titration are available in FUJIFILM Wako, which are valued by an international unit traceable evaluation method (SI traceable).
