PS-DVB Micron-Sized Particle Size Standards

Micron-Sized Particle Size Standards are synthesized from cross-linked polystyrene and divinylbenzene (PS-DVB), endowing the microspheres with exceptional durability and chemical/physical stability. These size standards exhibit a narrow particle size distribution and excellent monodispersity.
Packaged as aqueous suspensions in clean eye-dropper bottles, the solid content for each particle size has been pre-optimized to facilitate dispersion and user convenience.
The certified values of micron-sized particle size reference materials are determined via scanning electron microscopy (SEM) or microscopy with image analysis, with results traceable to national length standards. They are suitable for calibrating:

• Scanning/Transmission Electron Microscopes (SEM/TEM)
• Particle sizing instruments (e.g., laser diffraction analyzers, dynamic light scattering analyzers).
