| 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 to standardize and monitor instrument particle size. Also used: • to assess the effect of microplastics on zooplankton upon ingestion • to calibrate microfluidic device based on size measurements • in focused beam reflectance measurement (FBRM) based particle system characterization |
| 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: | This polystyrene-based microparticle (size: 20 μm) size standard is ideal for profiling particle size distribution (PSD) of test samples. |
