What is Zetasizer Nano ZS?
The Zetasizer Nano ZS is a high performance two angle particle, zeta-potential, and molecular size analyzer for the enhanced detection of aggregates and small particles. Samples may be measured at very low or high concentration using dynamic light scattering with ‘NIBS’ optics.
What is a Zetasizer?
The Zetasizer Nano range of instruments provides the ability to measure three characteristic of particles or molecules in a liquid medium. These three fundamental parameters are Particle size, Zeta potential and Molecular weight.
What is Malvern Zetasizer?
Malvern Zetasizer Ultra The Zetasizer Ultra, the most advanced light scattering system, delivers enhanced resolution, speed and ease-of-use for the measurement of particle and molecular size, particle charge and particle concentration.
How does Malvern Zetasizer work?
The Zetasizer Nano series performs molecular weight measurements using a process called Static Light Scattering (SLS). In a similar way to Dynamic Light Scattering – the size theory – the particles in a sample are illuminated by a light source such as a laser, with the particles scattering the light in all directions.
What is the principle of zetasizer?
The principle of dynamic light scattering is that fine particles and molecules that are in constant random thermal motion, called Brownian motion, diffuse at a speed related to their size, smaller particles diffusing faster than larger particles.
What is DLS technique?
Dynamic light scattering (DLS), sometimes referred to as Quasi Elastic Light Scattering (QELS), is a non-invasive, well-established technique for measuring the size and size distribution of molecules and particles typically in the submicron region, and with the latest technology, lower than 1nm.
What is Malvern particle size analyzer?
The Malvern Mastersizer 3000 is a laser diffraction particle size analyzer, suitable for measuring particle sizes 0.1 um – 3 mm. (Small particles have a small scattering angle, while large particles have a large scattering angle.) Using Mie theory, the data is used to calculate particle size distribution in a sample.
How can we reduce zeta potential?
Higher zeta potential values, either positive or negative, are necessary to ensure stability, and avoid aggregation of particles. Zeta potential can be altered by varying the stabilizer concentration, or by surface modification with cationic agents.
Is there a user manual for the zetasizer nano?
This user manual is a companion to the Zetasizer Nano Basic Guide, which gives Health and Safety, maintenance, troubleshooting and other vital information which all users must read. About this manual
