50 um – 2,400 um Particle size analysis range.  This system is designed for on-line use to determine particle size, shape and distribution, thereby eliminating the need for sieve analysis.

Related ASTM Standards:
• D8200 – Standard Practice for Creating a Correlation to Compare Particle Size Distribution Results of Proppants by Dynamic Imaging Analysis and Sieves. (D18.26)
• D8392 – Standard Practice for Calibration and Verification of Direct Imaging Analyzers Used for Particle Size and Shape Analysis of Catalytic Materials (D32.02)
• E2589 – Terminology Relating to Non-Sieving Methods of Powder Characterization. (E29.02)

Related ISO Standards:

Canty participates in the referenced ASTM subcommittees (D18.26, D32.02 and E29.02) in order to develop useful standards for imaging analyzers. Although the referenced standards are often particular to a type of particle, they can be generalized for use with many types of particles.
ISO9276-6 is widely used to describe shape parameters and provide corresponding formulae for calculation of values.
