An entry level system for the measurement of particle size and molecular size at a 90 degree scattering angle using Dynamic Light Scattering, also with the ability to measure zeta potential and electrophoretic mobility using Laser Doppler Microelectrophoresis, and molecular weight using Static Light Scattering.

 

The Zetasizer Nano ZS90 is the perfect lower cost solution  when the ultimate in sizing sensitivity is not necessary, or where identical results to a legacy system with 90 degree scattering optics is required.
- Size measurement from 0.3nm (diameter) to 5 microns using 90 degree scattering optics
- Zeta potential of proteins and particles from 3.8nm up to 100 microns (diameter) using patented M3-PALS technology
- Molecular weight measurement down to 9,800Da
- A Quality Factor gives confidence in the data
- The Expert advice report gives help to improve sample preparation or the measurement procedure
- 21CFR part 11 software option enables compliance with ER/ES
- Research software option gives access to further features and analysis algorithms for the light scattering specialist
- Automation of measurements using an autotitrator option
- Alternative laser, 50mW at 532nm for samples incompatible with the standard 633nm laser fitted.
- Optical filter option to improve measurements with fluorescent sample
- Temperature range extension option to 120ºC
