Safar Posted February 25, 2011 Posted February 25, 2011 I am trying to measure zeta potential of my particles wich are silicate based, the zeta potential is decreasing with time, in 1mM buffer, it starts with a positive 10 value and decreases to about -30 over 30 minutes. Is this a stability problem?
CharonY Posted February 25, 2011 Posted February 25, 2011 It appears so. One question would be whether the pH is stable over the time (considering the relative low concentration).
Safar Posted March 1, 2011 Author Posted March 1, 2011 I have tried it in higher conc. buffers upto 50mM but the results are still the same.
