Multisizer 4e Coulter Counter

The Multisizer 4e particle sizer and counter is the most accurate and flexible particle characterization device available, boasting an unparalleled sizing range of 0.2 - 1600 μm. The new 10 μm Aperture allows users to study sub-cellular and micro-particles as small as 200 nm, while the advanced noise reduction system for small apertures improves measurement accuracy.

Generated data are processed using patented digital pulse processing technology and can be saved and later re-analyzed. This technology provides ultra high resolution and accuracy unattainable through any other technologies: detection of 1 particle in 1 ml of a sample with the optimal instrument configuration. Analysis results are not dependent on particle shape, structure, or optical properties.

It uses the Coulter principle to detect particles via electrical zone sensing, regardless of the particle’s nature or optical properties. This makes it an ideal tool for detecting and counting a wide variety of particles, such as:

  • Mammalian cells
  • Bacteria
  • Yeast
  • Abrasives
  • Toner particles
  • Cell aggregates
  • Spheroids
  • Large protein aggregates

Choosing the Right Instrument for Cell Counting and Particle Characterization
Analyzing Mussel/Mollusk Propagation Using the Coulter Analyzer Multisizer 4e This application note details how the use of a Coulter Principle based instrument provides a major step forward in accurately verifying both the size of the feed and concentration for a fish hatchery.
The Coulter Principle for Outlier Detection in Highly Concentrated Solutions Particle characterization techniques generally fall into one of two categories: “ensemble” techniques (multiple par ticles are analyzed simultaneously), or “discrete” techniques (individual particles are measured one at a time)
Optimizing the Multisizer 4e Coulter Counter for use with Small Apertures The purpose of this application note is to provide some guidelines to facilitate successful testing with the Multisizer 4e when employing 30 µm and smaller.
