  2. Particle size analysis - Wikipedia

    en.wikipedia.org/wiki/Particle_size_analysis

    Particle size analysis, particle size measurement, or simply particle sizing, is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.

  3. Hegman gauge - Wikipedia

    en.wikipedia.org/wiki/Hegman_gauge

    The grooves decrease in depth from one end of the block to the other, according to a scale stamped next to them. A typical Hegman gauge is 170mm by 65mm by 15mm, with a channel of grooves running lengthwise, 12.5mm across and narrowing uniformly in depth from 100 μm to zero and used to determine particle size.

  4. Scanning mobility particle sizer - Wikipedia

    en.wikipedia.org/wiki/Scanning_mobility_particle...

    A scanning mobility particle sizer (SMPS) is an analytical instrument that measures the size and number concentration of aerosol particles with diameters from 2.5 nm to 1000 nm. [1] They employ a continuous, fast-scanning technique to provide high-resolution measurements.

  5. Sieve analysis - Wikipedia

    en.wikipedia.org/wiki/Sieve_analysis

    A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...

  6. Malvern Panalytical - Wikipedia

    en.wikipedia.org/wiki/Malvern_Panalytical

    The company produces technology for materials analysis and principal instruments designed to measure the size, shape and charge of particles. [11] Additional areas of development include equipment for rheology measurements, [3] [12] chemical imaging [13] and chromatography. [14] In 2017, they merged with PANalytical to form Malvern Panalytical ...

  7. Laser diffraction analysis - Wikipedia

    en.wikipedia.org/wiki/Laser_diffraction_analysis

    Laser diffraction analysis, also known as laser diffraction spectroscopy, is a technology that utilizes diffraction patterns of a laser beam passed through any object ranging from nanometers to millimeters in size [1] to quickly measure geometrical dimensions of a particle. This particle size analysis process does not depend on volumetric flow ...
