Beschreibung

General description

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.

Application

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.

Features and Benefits

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

Analysis Note

Für jede Charge werden genaue Werte der Partikelgröße und Standardabweichung mit einer Genauigkeit von 0,001 μm ermittelt. Die Größenbestimmung dieser Partikel befolgt die vom National Institute of Standards and Technology (NIST, USA) bzw. die vom Community Bureau of Reference (BCR) vorgeschriebenen Verfahren, insbes.:

• Transmissionselektronenmikroskopie (TEM)
• Rasterelektronenmikroskopie
• Lichtmikroskopie
• Coulter^™ Zähler mit MDF-System

Die Kalibrierung der Geräte wird anhand der NIST- bzw. BCR-Standards hinsichtlich der Partikelgröße durchgeführt.
