General description
This polystyrene-based microparticle (size: 20 μm) size standard is ideal for profiling particle size distribution (PSD) of test samples.
Application
Used to standardize and monitor instrument particle size.
Also used:
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
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.
