Introduction to the Zetasizer Nano ZS
The Zetasizer Nano ZS is a powerful particle characterization tool designed to help scientists, engineers and researchers to measure the size, shape and surface charge of molecular and colloidal particles at nano-scale. This device can be used to investigate drug formulations, monitor proteins during biotherapeutic development, characterize nanoparticles for nanomedicine research and assess the properties of traditional chemical products such as paints and pesticides.
The Zetasizer Nano ZS measures particles using two well-established particle characterization techniques – Dynamic Light Scattering (DLS) and Electrophoretic Light Scattering (ELS). DLS provides accurate measurements of particle size in the range from 1 nm to 8 μm. It does this by comparing the scattering pattern of laser light that is scattered by a sample solution when excited by a focused laser beam with theoretical pre-calculated data. ELS provides direct information about the zeta potential of particles between 0.05 – 400 mV. Here an applied electric field causes small particles in suspension to migrate towards one or other of two pin electrodes at different rates depending on its surface charge density, giving an indication of the magnitude and polarity of thatcharge.
In addition, The Zetasizer Nano ZS features Autosampler capability which simplifies sample processing enabling sample times even below 30 seconds per measurement point while maintaining accuracy over extended periods through automated mixing time control (ATC). This allows users access to results much faster than before as well as reliable automated data collection for long term processes such as today’s continuous manufacturing production runs. Additionally, sophisticated auto calibration routines enable workflow models which help reduce manual setup time significantly thereby increasing throughput further still without having negative impact on accuracy.
Overall, The Zetasizer Nano ZS is a versatile instrument not only because of its combined DLS/ELS capabilities but due to its intuitive software making it easier for non-specialists within laboratories or QC environments as well
What Does the Zetasizer Nano ZS Offer?
The Zetasizer Nano ZS is a unique and powerful instrument for measuring the physical and chemical properties of particles in suspension. It offers the ability to measure zeta potential, particle size, molecular weight, electrophoretic mobility, and dynamic light scattering (DLS), making it invaluable for critical research applications within colloid science, material sciences and related fields.
The Zetasizer Nano ZS uses light to capture images of suspended particles through its advanced Imaging Detection System (IDS). This system allows scientists to get dynamic visual feedback on how size and charge are developing in their samples. The IDS feature helps ensure consistent criteria for particle size measurement accuracy, something that can be especially important for determining agglomeration and sedimentation stability of colloidal systems in complex formulas.
By coupling the IDS with features such as zeta potential and Dynamic Light Scattering (DLS) measurements, users of the Zetasizer Nano ZS can gain even more insight into key factors like surface energy or equivalent ionic strength needed to predict settling rates over time. Not only does this allow researchers to assess the effects of different dispersants on colloid particle systems but also helps them better control formula-to-formula variability when working with complex fluid systems at industrial scale.
Assaying sample intensity by scanning across a broad range of angles also enables measurements up to 8 orders of magnitude faster than traditional techniques when used in combination with laser diffraction technology; creating unparalleled efficiency when it comes to analysis or optimization tasks requiring a large amount data points. Ultimately, this means that researchers can rapidly create detailed particle size distribution profiles that improve prediction accuracy of vital parameters involved in product life cycle stage management – from formulation development right through to end use performance replication.
In short, the Zetasizer Nano ZS delivers valuable results combined with flexible operation modes tailored towards improving formulator’s understanding of interactions between ingredients which ultimately create multiple advantages throughout all stages from product design
