Leírás

Általános leírás

Monodisperse polystyrene based micro particles (size: 4.0 μm) are a size standard, designed to identify the particle size distribution (PSD) of test samples.

Alkalmazás

Used to validate and monitor the performance of particle sizing equipment. Also used to produce armored bubbles—interfacial composite materials (ICM) formed by embedding with air bubbles.

Tulajdonságok és előnyök

• suitable for routine instrument calibration checks and corrections
• available in 5 mL & 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.
