Megabead NIST Traceable Particle Size Standards

  • Packaging Size

  • Nominal Size

  • Size Range

  • Method

: ​15 ml

: 10.0 - 175.0 µm

: 9.50 - 185.00 µm

: Single Particle Optical Sensing (SPOS)

  • Single Particle Optical Sensing (SPOS) is a combination of light extinction and light scattering.

  • Individual particles pass through a small optical sensing region one at a time and produce a detecting pulse.

  • The magnitude of the pulse depends on the size of the particle.

  • The particle size distribution plot of the sample is constructed one particle at a time by comparing the detected pulse heights with a standard calibration curve based on NIST traceable particles of known diameters.
