CAS-E - Charge Analyzing System

The CAS-E particle charge measurement system is especially designed for customers who would like to use their existing external titrator or prefer hand titration. 

With the help of the CAS-E, cationic / anionic and acid / base demands of aqueous charge systems can be determined.

Both, Streaming Potential (mV) and pH can be measured simultaneously, making it possible to easily determine isoelectric and flocculation points of a sample.

The CAS-E system comes with a connection for optional pH detector. This feature allows for the determination of the isoelectric point (IEP), but also the examination of the correlation between pH, Titrant Demand and Streaming Potential.
