General description
Monodisperse polystyrene based micro particles (size: 8.0 μm) are a particle size standard, ideal to determine the particle size distribution (PSD) of test samples.
Application
Intended for use in validation and monitoring of the performance of particle sizing instruments.
It′s also used to:
It′s also used to:
- standardize methods of size-dependent chromatographic separations.
- characterize electrical impedance spectroscopy (EIS) performance of microfluidic device by size measurement.
Features and Benefits
- suitable for routine instrument calibration checks and corrections
- available in 5 mL pack size as a neat sample
