Itrax XRF Scanner MC

Cox_Itrax_XRF_Scanner_MC_2.png

Excellent performance

Itrax XRF Scanner MC is a new construction dedicated to CS-XRF Continuous Scanning XRF of samples for chemical elements from Na and all the way up to Uranium in drill cores. It can also be used to scan sediment cores, and regardless of sample type, it offers the highest available scan speed combined with very good sensitivity across the whole range of chemical elements. It is our latest construction, featuring cutting edge XRF with excellent performance, so that all found elements from bulk to trace level are determined in the best possible way and at the same time, even when the XRF is challenged by a highly variable sample matrix. The first instrument of this new construction was installed 2018 at British Geological Survey in Nottingham, UK, and you also find it in the Oil Industry.

Dedicated to volume scanning

This scanner is designed for routine scanning of large volumes of cores, offering smooth core handling and batch job support. MC stands for Multi Core, and this scanner can be loaded with a set of cores, whether in a core box or not. Cores with a length up to 1250 millimeters and a diameter up to 127 millimeters are accepted. An added sample width of up to 450 millimeters can be inserted at the time.

Cutting edge XRF

Itrax XRF scanners provides continuous chemical element data that have a documented good accordance with traditional XRF analysis. Add to this the speed of analysis as well as the minimized sample preparation that Itrax XRF scanning offers, saving so much time and work. A drill core can be scanned with good results without further sample preparation. Scan speed is optimized by the short time needed for a reliable measurement, and by the continuous, non contact scanning where no stopping at each point to move the scan head up and down is required. All elements of interest are determined simultaneously in one analysis, and with highest sensitivity. Quantification takes no longer time, and there is no need for calibration with standards for every analysis. This removes the need for time consuming multiple analyses at different voltages. The ability to determine Na is important for good quantitative results, and the trace element info that you get at the same time can provide so much proxy information.

Adapted to cores

Itrax XRF Scanner MC can scan along a sample, without missing any part. It can also be programmed to perform different sections of a scan along parallel tracks, in order to avoid sample parts that contain damages, etc. Each instrument is equipped with high performance XRF and a RGB optical camera that registers detailed sample images. A laser distance meter determines the sample topography, allowing for analyses that have correct distance to the sample surface at each and every increment.

Highest speed with variable increments

Itrax offers a unique, cutting edge feature where the analytical speed and performance is maintained as increment size is decreased. For the XRF scanner MC, this means that the very short measuring time of one second per increment can be applied from centimeter increments and all the way down to 1 millimeter.  Within this range, the increment size has no impact on the speed/data quality ratio. Even higher lateral resolution can be achieved by a slit system.

Ready for more than cores

The Itrax XRF Scanner MC is also equipped for analysis of tablets and powder samples in plastic cups, like in the photo to the left. Batches of powder samples and pressed tablets can be analyzed for elements concentrations in powdered material, e.g. from hammer drilling. The software supports bar code, QR code and several other formats of sample tagging for easy and safe sample ID.

Strong software support

Another key feature of this scanner is that it is delivered with robust software for element quantification. It can handle large shifts in sample matrices and still deliver good quality quantitative estimates for any concentration from trace level and up to the amounts found in mining and matrix elements.  The software is straightforward and easy to use, while still flexible with user controlled analytical settings. Standard batch job settings can be stored in order to make it easy to initiate a standard batch job over and over again. Software for data display of whole bore holes is also delivered with each instrument.

Overview and details

The analytical resolution is variable from 10-1 millimeter for maximum flexibility, so that the scanner can be adapted to different requirements. Standard XRF scan time for mineral drill cores is 100 seconds per meter, allowing for fast yet precise overview scans where the data can be described as amount per meter of the determined elements. Scans with higher precision, like required for sedimentary materials in petroleum applications, only take a few seconds per analytical point to determine a wide range of elements from Na-U.

Swedish quality seal

With a robust, high quality construction Made in Sweden, and built for 24/7 operation, this XRF scanner does a great job in a permanent lab setup, as well as in a lab container for field work.
