Xrf Analysis

In on–stream X–ray fluorescence analysis of ore slurries, the effects due to variation in the particle-size of solids can cause appreciable and sometimes major errors in the measured concentration of an element to be determined. Weight percentage of slurry ore grains with diameter smaller than 75 um (called later W75) is commonly used as measure of ore fineness and can be determined using particle-size analyzers. A method of correcting for W75 variaition is highly desireable, particularly in a case when high analysis accuracy is required for economical reasons.

Laser Induced Breakdown

Calibration aiming at quantitative analysis of complex samples is one of the most difficult issues in laser-induced breakdown spectroscopy (LIBS) due to matrix interferences, heterogeneity, and sample particle size effects.

Laser Induced Breakdown

The uncertainty of the spectral data is one of the most important issues for LIBS. To reduce the uncertainty, an imaging system was deployed and a model was built based on both the spectral signal and the positional information in this work.
