Nano-particle Size Analyzer units are designed for nanoparticle size analysis using dynamic light scattering and Brownian motion principles for colloidal and nanomaterial characterization. The range includes systems with measuring ranges from 1 nm to 10000 nm and test speeds below 5 minutes for rapid particle distribution evaluation. Models support precision nanoparticle size analysis workflows in pharmaceutical, biotechnology, chemical, and material research applications.
FAQ for Nano-particle Size Analyzer
1: What is a Nano-Particle Size Analyzer used for?
It is used to measure the size distribution of nanoparticles in liquid or powder form with high precision.
2: Why is DLS suitable for nanoparticle analysis?
Dynamic Light Scattering is highly sensitive and non-destructive, making it ideal for measuring small particles in suspensions and emulsions with excellent accuracy and reproducibility.
3: What role does the photomultiplier detector play in the analyzer?
The photomultiplier detector detects the scattered light from particles with extremely high sensitivity, enabling precise size measurement even at low concentrations.
4: How does the analyzer determine particle size?
The analyzer calculates particle diameter based on Brownian motion and applies the Stokes-Einstein equation to determine the hydrodynamic diameter of nanoparticles.
5: What is the role of the stable light system in this analyzer?
The stable light system, typically a laser diode, ensures consistent light intensity and wavelength which are essential for accurate and repeatable light scattering measurements.
