Impact of manual sample preparation on efficiency of grinding Abstract Sample preparation for XRF analysis is often done manually by crushing, splitting, pulverizing, and pelletizing. Here we show that the way in which the grinding vessel is loaded with sample material has a significant impact on the pulverizing efficiency.

SAMPLE PREPARATION The method of sample preparation is nondestructive (except for grinding) and the sediment fractions can be recovered for further testing or refinement. An exception to this is that calcite, aragonite and, to some extent, dolomite, gypsum, and anhydrite are dissolved in the decalcifiion process.
