Measuring Zeta Potential of Non-aqueous Suspensions

Sub-micron particles suspended in liquid medium are regularly utilized in many industries, from food and pharmaceutical production to lubricants for machinery.  The stability of these suspensions is vital to their function and shelf-life.  The typical way to characterize the stability of a suspension is to measure the zeta potential of the suspension.

So what is zeta potential and how is it used to determine suspension stability? Continue reading
