The colored elements can be analyzed by XRF. There are multiple advantages to energy dispersive XRF analyzers such as the Shimadzu EDX-7000. It can analyze solids, liquids, and powders with very little sample preparation or pretreatment. The measurement range is low parts per million (depending on the element) to 100%. Analysis times are 1-10 minutes. It sits right on the tabletop and is capable of rapid semi-quantitative analysis without standards, or very accurate quantitative analysis using standards.

 

Table 1 is a comparison of XRF data with a certified reference cement.
