설명

일반 설명

Polymethacrylate-based microparticles (size: 20 μm) are a size standard, ideal to determine particle size distribution (PSD) profile of a particle system.

애플리케이션

Applicable for calibrating and validating particle size analyzers.
It can be used to:

• count and differentiate microscale particles using Coulter-type sensor
• detect and measure the micropolymethacrylate-laden analytes

특징 및 장점

• suitable for routine instrument calibration checks, testing and corrections
• available in 5 mL pack size as a neat sample

분석 메모

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.
