Monitoring Size and Zeta Potential Changes with Temperature at Different pHs for Magnetic Microspheres

2024-02-06Application Note

Magnetic microspheres are composite microspheres formed by combining magnetic inorganic particles with organic polymers. In this application note, the BeNano 90 Zeta was utilized to measure the size and zeta potential of a magnetic microsphere sample. The study investigated various pH levels (3, 6, and 9) and different temperature conditions. The findings suggest that the stability of the magnetic microspheres system is notably robust at pH 6 and 9, displaying minimal variations in particle size as temperature changes. However, at pH 3, the system's stability is more susceptible to temperature fluctuations.
