Particle counters are used to count a certain type of particle in a variety of material types. Aerosol counters determine size and number of particles in the air and are often used to determine air quality or check clean rooms for contamination. Liquid counters count particles in liquid such as when analyzing drinking water quality or purity of aqueous drugs. Finally, solid counters measure dry particles and are often used to analyze protein aggregation or material quality in industrial labs.
Based on the type of material and the size of the particles being analyzed, instruments differ in the detection method employed. These methods include: light blocking or scattering, the Coulter principle which is based on changes in electrical impedance, and direct imaging. Choice of detection method will depend on the application the counter is being used for.

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
Features
