Description

General description

Polymethacrylate-based microparticles are a size standard, fit for the analysis of particle size distribution (PSD) of test samples.
The particle diameter of 30 μm is measured using Coulter Multisizer.

Application

Used to develop and calibrate particle size analyzers.
Also used as a test standard in imaging application such as coherent anti-Stokes Raman scattering (CARS) microspectroscopy.

Features and Benefits

• suitable for routine instrument calibration checks, testing and corrections
• traceable to Community Bureau of Reference (BCR) standards
• available in 5 mL pack size as a neat sample

Analysis Note

The exact values for particle size and standard deviation are determined for each lot and may be found on the certificate of analysis. These values are determined with an accuracy of 0.01 μm (Coulter Multisizer). Polymethacrylate based particles have a narrow size distribution and spherical shape. They are stable at temperatures of up to 100 °C Density is 1.22 g/cm³. The surface is negatively charged. Good biocompatibility and reduced nonspecific protein binding are characteristic.
