The PCA measures colloidal and ionic charge in liquid samples, and determines anionic or cationic levels. A digital readout provides a convenient reference for the user to know the charge value of the sample. The instrument will with automatic or manual titration, quantify the charge demand in milli-equivalents per ml.
The Micrometrix PCA will test liquids and suspensions of small colloidal particles. We recommend screening samples containing very large particles and fibers larger than 100 microns, prior to measurement. An automatic titrator connected to the millivolt output of the PCA will perform fully automatic cationic or anionic titrations where the endpoint is zero mVolts.
