The relative proportion of K-/Na/-Ca-feldspar is estimated as well as the possible quartz contamination. Interested? Get in touch! Contact now This module allows an estimate of the mineral composition of feldspar samples. The relative proportion of K-/Na/-Ca-feldspar is estimated as well as the possible quartz contamination. The XRF unit consist of: Amptek X-123 complete spectrometer with SDD Complete X-ray spectrometer Amptek MINI-X USB controlled X-ray tube Software extension for XRF analysis: A special program for analyzing the XRF data for conversion of the result onto the ternary diagram of K-/Na/-Ca-feldspar and providing an estimate of quartz contamination. Reference samples for performing and maintaining the K-/Na/-Ca-feldspar calibration are included. Special sample cups: Sample cups specially made from molybdenum metal (200 pieces will be supplied) Note: XRF unit requires vacuum pump.
