| Analysis Note: |
For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.001 μm. The size determination of these particles follows procedures described by National Institute of Standards and Technology (NIST, USA) respectively by the Community Bureau of Reference (BCR), esp.:
• Transmission electron microscopy (TEM)
• Scanning electron microscope
• Light microscopy
• Coulter™ counter with MDF-system
Calibration of equipment is carried out with NIST-respectively BCR-particle size standards. |
| Application: |
Used to calibrate and monitor the performance of particle size analyzers. |
| Features and Benefits: |
• suitable for routine instrument calibration checks, testing and corrections
• available in 5 mL and 10 mL pack sizes as neat samples
|
| General description: |
Monodisperse polystyrene based micro particles (size: 200 μm) are a size standard, ideal for profiling particle size distribution (PSD) of a particle system.
The particle diameter of 200 μm is characterized using Olympus optical microscope. The measuring instruments are calibrated using standards obtained from the Community Bureau of Reference (BCR, Belgium: Standards RM 165, 166 or 167) and from the NIST (SRM 1690, 1691 or 1692). |
