Malvern:
Zetasizer Nano, mV and APS
Dynamic Light Scattering
The premium ranges of sub-micron instruments with the
highest sensitivity and widest range of measured
parameters and options available. This is the world’s most
popular system for the measurement of particle sizes from
0.6nm and molecular size from 980 Da using Dynamic
Light Scattering. Add to this zeta potential and
electrophoretic mobility using Laser Doppler
Microelectrophoresis, and molecular weight using Static
Light Scattering, and the Zetasizer Nano range is a
formidable system.
A new option for the Zetasizer range is the
Solid Surface Cell
that facilitates measuring the Zp of a
surface or adsorbed material using tracer particles and stepping the measurement position incremen-
tally from the surface in a series of measurements—and extrapolating back to the real surface.
Also new is the tracer-particle
DWS
Microrheology
facility
launched with the ZSP and
available as a retrofit for all
Zetasizer Nano ZS users. This
software is for studying vis-
coelastic properties of sam-
ples in dilute systems.
The
Nano ZSP
also features a
completely new
Protein meas-
urement
package for protein
charge, protein mobility and
protein interactions.
