Testa Analytical Solutions e.K. has introduced a Surface Zeta Potential option for its NanoBrook range of zeta potential analysers. Adding the new surface zeta potential option to a Nanobrook analyser allows you to measure the electrical charge on materials like coated glass, plastic, tape, or other flexible surfaces. The system uses known probe particles and purpose-designed electrode to calculate surface zeta potential. Leveraging proprietary phase analysis light scattering (PALS) technology...
