| Analysis Note: | For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.001 μm. The size determination of these particles follows procedures described by National Institute of Standards and Technology (NIST, USA) respectively by the Community Bureau of Reference (BCR), esp.: • Transmission electron microscopy (TEM) • Scanning electron microscope • Light microscopy • Coulter™ counter with MDF-system Calibration of equipment is carried out with NIST-respectively BCR-particle size standards. |
| Application: | Used to calibrate and validate the performance of particle size analyzers. Monodisperse polystyrene latex particles can also be used to: • validate the Airy Disc First Fringe (ADFF) analysis technique based on size measurements • study the size effect of polystyrene microplastics on the sorption of organic contaminants |
| Features and Benefits: | • suitable for routine instrument calibration checks, testing and corrections • available in 5 mL pack size as a neat sample |
| General description: | Monodisperse polystyrene based micro particles (size: 30 μm) are a particle size standard, ideal for characterizing particle size distribution (PSD) of test samples. |
