Method Reference:
Internally-developed method
Method Description:
The instrument provides a particle size distribution without the physical separation required by sieves. Particle size distributions are characterized by percentages of a sample in up to 140 channels covering a total range of 0.12 to 1500 micrometers diameter. This range enables the analysis of smaller particles than can be sized with sieve analysis. An added advantage is that emulsions, suspensions, and pastes can also be tested, as long as a compatible carrier fluid is available. Care must be exercised with non-spherical particles, as the size will be expressed as an equivalent spherical diameter.
Particles are typically dispersed in a compatible liquid carrier fluid (a liquid that does not dissolve or agglomerate particles). Atypical samples may require special handling or technique.
Information Required by Submitter:
Composition of the sample. Samples need to be either diluted with the continuous phase liquid for emulsions or powders must be dispersed into a solvent that does not dissolve or react with the sample.
Additional Information:
Microtrac instrument measures particle size by Laser Diffraction. The test is designed for spherical shaped particles.
