Typically making zeta potential measurements in organic (non polar) solvents requires much higher sensitivity than in aqueous (polar) solutions. The Nanobrook Zeta PALS analyser achieves this using phase analysis light scattering (PALS). According to the company the Nanobrook Zeta PALS can be used to make zeta potential measurements up to 1,000 times more sensitive than traditional light scattering methods based on the shifted frequency spectrum. Made of PEEK with a Palladium (Pd) electrode assembly, the Nanobrook Zeta PALS measurement cell is resistant to the widest range possible of solvents. As it can be read in a press release, it offers excellent chemical stability, easy cleaning and long-term top performance.
