설명

일반 설명

Monodisperse polystyrene based micro particles (size: 3.0 μm) are a size standard, designed to identify the particle size distribution (PSD) profile of test samples.

애플리케이션

Used to validate and monitor the performance of particle sizing equipment.
Also used:

• in acoustic traps to study the effect of non-contact retention of microparticles on trapping performance of lab on chip systems
• to synthesize microsphere-based interferometric optical probe called reflectophore

특징 및 장점

• suitable for routine instrument calibration checks 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.
