 Main information about ElvaX Geo
Instant on-site elemental analysis is one of the necessities of the modern mining industry. ElvaX Geo offers you accurate data and ease of operation during geo exploration or quality assurance. The instrument is designed specifically for long non-stop convenient operation. The unique 800 mm2 analytical spot analysis increases averaging of inhomogeneous samples. A composite pole helps you keep a comfortable body position during operation and enables you to analyze hard-toreach places. This form factor allows for uninterrupted measurement during slow walking while measurement results are communicated to the operator through headphones. ElvaX Geo is operated through a PDA in a protective enclosure, which can be put underneath outer garment in case of extreme climatic conditions. The Li-Ion Battery can be hidden as well. ElvaX Geo software uses both the Fundamental Parameters and the Empirical Calibration Methods. Fundamental parameters analysis of unknown samples without empirical calibration is remarkably accurate. However every instrument is calibrated for the basic mineral types with NIST or NIST traceable samples. ElvaX Geo demonstrates excellent limits of detection and repeatability.
