Laser scattering particle size distribution analyzer.
Laser scattering particle size distribution analyzer.
Dynamic light scattering dls is a technique in physics that can be used to determine the size distribution profile of small particles in suspension or polymers in solution.
This latest evolution in the la series advances scientific knowledge for tomorrow s world through intuitive software unique accessories and high performance.
Laser diffraction uses mie theory of light scattering to calculate the particle size distribution assuming a volume equivalent sphere model.
Laser diffraction analysis also known as laser diffraction spectroscopy is a technology that utilizes diffraction patterns of a laser beam passed through any object ranging from nanometers to millimeters in size to quickly measure geometrical dimensions of a particle.
This process does not depend on volumetric flow rate the amount of particles that passes through a surface over time.
Bettersizer st laser scattering particle size distribution analyzer includes the patented dual lens optical system dlos which provides a compact design without resorting to folding optics that are susceptible to misalignment caused by vibrations often present in most industrial labs.
The la 960 continues horiba s proud tradition of leading the industry with innovative design.
In the scope of dls temporal fluctuations are usually analyzed by means of the intensity or photon auto correlation function also known as photon correlation spectroscopy or quasi elastic light scattering.
