Descrição geral

Monodisperse polystyrene based micro particles (size: 10 μm) are a particle size standard, ideal for characterizing particle size distribution (PSD) of test samples.

Aplicação

Used to calibrate and validate the performance of particle sizing instruments.
Monodisperse polystyrene latex particles are also used to:
  • fabricate microsphere-based interferometric optical probe called reflectophore
  • validate the Airy Disc First Fringe (ADFF) analysis technique based on size measurements
  • qualify spectral reflectometry (SpeRe) instrument by using scanning electron microscopy (SEM)

Características e benefícios

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 mL and 10 mL pack sizes as neat samples

Nota de análise

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.

Fluorescent optical probes have rapidly transformed our understanding of complex biological systems by providing specific information on biological targets in the natural living state. However, their utility is often limited by insufficient brightness, photostability, and multiplexing capacity. Here, we report
