Description

Description générale

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:

• to assess the effect of microplastics on zooplankton upon ingestion[1]
• to calibrate microfluidic device based on size measurements[2]
• in focused beam reflectance measurement (FBRM) based particle system characterization[3]

Caractéristiques et avantages

• suitable for routine instrument calibration checks, testing and corrections
• available in 5 and 10 mL pack sizes as neat samples

Remarque sur l'analyse

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.
