Analysis Note
For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.
Application
Used for equipment particle size monitoring and validation.
Also used to:
investigate the impact of polystyrene microplastics on marine biota and organic matter[1][2]
study optical confinement in optofluidic laser measurements[3]
Features and Benefits
suitable for routine instrument calibration checks, testing and corrections
available in 5 and 10 mL pack sizes as neat samples
General description
Polystyrene based microparticles (size: 30 μm) are a particle size standard, ideal to determine particle size distribution (PSD) of test samples.
