Leírás

Általános leírás

Monodisperse polystyrene based micro particles (size: 1 μm) are a particle size standard, ideal for characterizing particle size distribution (PSD) of test samples.

Alkalmazás

Used to test the performance of particle sizers and particle counters.
Monodisperse polystyrene latex particles are also used to calibrate:

• Airy Disc First Fringe (ADFF) analysis method based on size measurements
• Aerosol instruments

Tulajdonságok és előnyök

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

Analízis megjegyzés

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.
