These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution. The absorbance imaginary component for minerals and metal oxides is normally taken as 0. Standards Subsctiption may be the perfect solution. The angle asgm intensity of laser light scattered by the particles are selectively measured to permit calculation of a volume distribution using light-scattering techniques.

Several manufacturers of testing equipment now have units based on these principles. Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made.

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 angle and intensity of laser light scattered by the particles are selectively measured to permit calculation of a volume distribution using light-scattering techniques.

Therefore, comparison of results from different instruments may be misleading. The technique is capable of measuring particles above and below this range.

Many of the published values were measured at A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range are present. The absorbance imaginary component for minerals and metal oxides is normally taken as 0.

For example, kaolinite measured at Although each type of testing equipment utilizes the same basic principles for light scattering as a function of particle size, different assumptions pertinent to application of the theory and different models for converting light measurements to particle size, may lead to different results for each instrument.

ASTM E e These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution. Already Subscribed to this document.

The axtm 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. The results of any particle sizing method should be used only in a relative sense and should not be regarded as absolute when comparing results obtained by other methods.
