설명

일반 설명

Monodisperse polystyrene based micro particles (size: 12.0 μm) are a particle size standard, designed to identify the particle size distribution (PSD) profile of test samples.

애플리케이션

Used to calibrate, qualify and monitor the performance of particle size analyzers, surface scanning instruments and particle counters.
Also used:

• in acoustic traps to study the effect of particle detection on trapping performance of lab on a chip systems
• as a reference of known dimensions to characterize real-time imaging systems
• as a calibration standard to validate the Airy Disc First Fringe (ADFF) analysis technique based on size measurements.

특징 및 장점

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

분석 메모

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.
