The amount of grinding aid used depends on the application and is usually between 2 % and 10 % of the sample quantity. Too much grinding aid results in intensities decrease and increases the detection limits of the analysis.
Often the moisture content, and thus, the chemical composition of a solid is altered during grinding and crushing (Dean, 1995). Decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating.
