Accurate Submicron Particle Sizing Using Photon Correlation Spectroscopy (PCS)
If particles in the submicron range are part of your production or product development process, measurement and control of particle size is important to you. You need an analyzer that can reliably detect the component populations in your sample every time. The N5 Submicron Particle Size Analyzer uses Photon Correlation Spectroscopy (PCS) , which determines particle size by measuring the rate of fluctuations in laser light intensity scattered by particles as they diffuse through a fluid. PCS is the only nondestructive method for measuring particle size down to a few nanometers, and the N5 is the only commercially available PCS analyzer that won't leave you wondering whether or not you really know what's in your sample.
Only multi-angle PCS analysis can reveal more accurately all the particle populations in your sample.
The N5 is the only PCS analyzer that uses six fixed measurement angles. Most PCS analyzers perform measurements at only 90 degrees. Because submicron particles scatter light in patterns depending on particle size, larger particles may be difficult to detect at 90 degrees if the sample contains a large number of smaller particles. Similarly, any population of particles that scatter weakly at a certain angle may be masked by particles with strong scattering at that angle. For this reason, single or dual angle PCS instruments provide only a partial view of your sample. Adjustable-angle instruments (goniometers) are prone to inaccuracy, in addition to being cumbersome.
Whether you are trying to characterize the results of a process in R&D, or monitoring for contamination on the production line, only the multi-angle N5 can consistently and accurately characterize your sample.
