| Description | Handheld X-ray spectrometers for field analysis have already become devices commonly used in environmental sciences to analyse a relatively broadspectrum of chemical elements, for example, in recent sediments and soils. The article describes the possibility of utilizing such instruments for the evaluation of cement raw materials, using as examples limestone andshale minedin Mokrá quarry in the southern part of the Moravian Karst. Measurement results using the "outdoor" XRF Analyser DELTA PREMIUM (manufacturedby Olympus Innov-X Systems, Inc.) were compared with the data obtained from significantly more sensitive and accurate methodICP-OES/MS in Acme Analytical Laboratories Ltd(Vancouver, Canada). This comparison of data has shown that the use of XRF analyzer in "GEOCHEM" mode makes a relatively accurate quantitative determination of Al, Si, P, S, K, Ca, Ti, Mn and e possible in the studied material, using the following procedure. Measurements by XRF analyzer on essentially flat (fracture) surfaces and surfaces of the cut plates showed that although there are differences in the results of analyses carried out repeatedly under identical conditions on the same areas, the differences are not substantial. On very rugged surfaces, the measurements are not comparable. |
