Electrophoretic Mobility

The Möbiuζ from Wyatt measures electrophoretic mobility of macromolecules and particles via phase analysis light scattering (PALS). Simultaneously it measures size via dynamic light scattering (DLS). The combination of mobility + size permits calculation of the zeta potential, an indicator of nanoparticle stability in suspension. The Möbiuζ incorporates a flow cell for connection to an autosampler. It may also be used in manual mode, either with a dip electrode or by injecting sample into the cell with a syringe.

Möbiuζ®

Wyatt Technology's Möbiuζ® is the first and only light scattering instrument that makes reliable, reproducible, and non-destructive electrophoretic mobility measurements of macromolecules as small as 2 nm in radius (as well as micron-size nanoparticles) in most aqueous buffers.
