Zetasizer Nano S, a dynamic light scattering system from Malvern Panalytical, combines the functions of both particle size analyzer and molecular weight analyzer. The system is user-friendly, versatile, and delivers high performance. It can be used for detecting aggregates, measuring dilute or high concentration samples, as well as for measuring molecular size and molecular weight.
The Zetasizer Nano S has the same sizing capability as the Zetasizer Nano Z and perfect for applications where the widest size range and highest sensitivity is required.
The main features of the Zetasizer Nano S are:
Sample concentrations from 0.1 ppm to 40% w/v
Automated temperature trend measurements
Second virial coefficient measurement for solubility
Molecular weight measurement down to 980 Da.
Size measurement from 0.3 nm (diameter) to 10 µm using Non-Invasive Back Scatter (NIBS) technology
Alternative laser, 50 mW at 532 nm for samples incompatible with the usual 633 nm laser fitted
Autotitrator option allows automation of measurements
Optical filter option to enhance measurements with fluorescent sample
21CFR part 11 software option allows compliance with ER/ES
Temperature range extension option to 120ºC
Systems can be upgraded to include zeta potential
Protein size measurement as dilute as 0.1 mg/mL (Lysozyme)
Flow mode capability to enable use as a GPC/SEC detector
Research software option offers access to additional features and analysis algorithms for the light scattering specialist
Expert advice report helps improve sample preparation or measurement process
We very much value the customer service and training opportunities from Malvern Panalytical, in particular, the rapid diagnosis of any issues through direct internet connection with the Malvern Panalytical customer service team has prevented us from suffering production downtime.
