A series of downloadable notes describing applications of the Zetasizer Nano system in the characterisation of polymers, proteins and other biomaterial is available on the Malvern website
Malvern's Zetasizer Nano measures particle size, zeta potential and molecular weight of nano-sized particles and molecules, with all three measurements offered in a single, compact instrument.
The Zetasizer Nano simplifies the size measurement and stability characterisation of a wide range of disperse systems and molecules in solution.
The use of patented Nibs (non invasive back scatter) technology enables particle size measurement at the high sensitivity necessary for small and poorly scattering molecules, such as proteins and polymers.
It also allows measurement at high concentrations of up to 20%w/v, so that samples including emulsions, pigments and toners require little or no dilution.
Measuring particle size from 0.6nm to 6 micron, it requires as little as 12 microliters of sample. Malvern's M3-Pals technology for zeta potential measurement combines second-generation implementation of phase analysis light scattering with Malvern's patented M3 measurement technology.
It provides the highest accuracy over a wide range of applications and allows full automation of the measurement process.
Measurement of absolute molecular weight using the classical Debye plot is supported by a standard operating procedure that guides the user, and can be completely automated using the new MPT-2 autotitrator.
