Furthermore, any particles which ashm outside the size measurement range of the instrument will be ignored, causing an increase in the reported percentages within the detectable range.

ASTM Methods – Particle Size Analysis | Micromeritics

The absorbance imaginary component for minerals and metal oxides is normally taken as 0. The angle and intensity of laser light scattered by the particles are selectively measured to permit calculation of a volume distribution using light-scattering techniques.

The results are strongly influenced by physical principles employed by each method of particle size analysis. Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made. Standards Subsctiption may be the perfect solution. Therefore, comparison of results from different instruments may be misleading. Link to Active This link will always route to the current Active version of the standard.

A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range are present.

Add to Alert PDF. For example, kaolinite measured at It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The technique is capable of measuring particles above and below this range. As the voice of the U. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution.
