The new FPA touch! Fiber Potential Analyzer combines proven methods of Zeta Potential measurement with the known great simplicity of handling and functioning of the previous FPA versions, but enhanced with new features and an immense reduction in weight and size.
Surface charges of fibers, fillers, particles or colloidally dissolved substances in stock suspension are defined by the Zeta Potential on their surfaces. The charge of the stock suspension can be split into the colloidal and particle charge, measured with the CAS touch! Charge Analyzing System, while the fiber and filler charge is measured with the FPA touch! Fiber Potential Analyzer. All both charge levels together define the overall Zeta Potential of fiber suspensions.
