Description
The Malvern Zetasizer Nano ZS is a high-performance analyser designed for precise measurement of particle size, zeta potential, and molecular size. Utilising advanced two-angle dynamic light scattering (DLS) with NIBS (Non-Invasive Back Scatter) optics, it delivers enhanced sensitivity for detecting aggregates and small particles across a wide concentration range. This system offers exceptional versatility, with a size measurement range from 0.3 nm to 10 µm and zeta potential measurement from 3.8 nm to 100 µm. It supports both low and high concentration samples, making it ideal for a broad spectrum of applications. The flow mode option allows seamless integration with Size Exclusion Chromatography (SEC) or Field Flow Fractionation (FFF) systems, enabling real-time detection of protein or nanoparticle size.
The Zetasizer Nano ZS also offers a comprehensive suite of measurement capabilities, including particle size analysis (0.6–6000 nm), zeta potential analysis (-150 to +150 mV), surface zeta potential, and kinetics/trend monitoring. It operates within a temperature range of 0°C to 90°C, and requires only 12–500 µL for size measurements or 1 mL for zeta potential.
With first readings in just 15 seconds and intuitive operation, the Zetasizer Nano ZS is a powerful tool for researchers seeking accuracy, efficiency, and flexibility in particle characterisation.
