General description
Monodisperse polystyrene based micro particles (size: 6.0 μm) are a particle size standard, ideal for profiling particle size distribution (PSD) of test samples.
Application
Used to calibrate, qualify and monitor the performance of particle size analyzers, surface scanning instruments and particle counters.
Monodisperse polystyrene latex particles can also be used to:
Monodisperse polystyrene latex particles can also be used to:
- investigate their effect on laser-induced breakdown spectroscopy (LIBS) emissions.
- study the effect of polystyrene microplastics on microalgal photosynthesis and growth and oyster reproduction.
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
