General description

Polymethacrylate-based microparticles (size: 50 μm) are a particle size standard, ideal to identify the particle size distribution (PSD) profile of test samples.

Application

Used for calibrating and monitoring particle size analyzers.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Features and Benefits

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 10 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.
