The N5 Submicron Particle Size Analyzer's 25 mW output laser allows analysis of samples in the 3 nm to 3 μm sizes range, samples that can be difficult to measure due to their weak scattering nature. PCS control software offers an array of tools to make operation flexible, easy and straight forward. The system is 21 CFR part 11 compliant and offers user definable standard operating methods and procedures. It provides fully automated molecular weight analysis, raw autocorrelation data export, multi-angle measurements, and fingerprint analyses for the determination of contaminants.
