Monitoring the Stability of Colloidal Silica Solutions Over Time using the SZ-100V2

In this application note, we used the SZ-100V2 to evaluate the stability of LUDOX® TM-50, a colloidal silica slurry. Two samples were analyzed: one from a newly opened bottle ("Fresh LUDOX®") and one from a bottle that had been opened and stored for over a year ("Aged LUDOX®"). By measuring and comparing the zeta potential and particle size of these samples, we demonstrate how the SZ-100V2 can effectively monitor the stability of colloidal silica.
