Itrax XRF Core Scanner
Includes a combination of techniques
Itrax Core Scanner combines scanning XRF multi element analytical scanning, x-ray radiographic images, and high quality optical images from a RGB line camera with crossed polarizing filters. Magnetic susceptibility measurements can also be added.
Offers a wide range of advantages
This instrument really excels in terms of speed and data quality, especially when it comes to millimeter level and sub millimeter increment scanning (see example at the page bottom). The scanning step size is variable in the 10-0.2 (0.1) millimeter range. This flexibility allows for quick overview scans as well as detailed high resolution scans. Itrax Core Scanner has a unique and very useful feature in that it does not loose speed as the step size is decreased, all the way down to 0.2 (0.1) millimeter.
The built-in x-ray radiography is a useful complement to the XRF, since it shows an image of the often small variations in density variation and chemistry along the sample, allowing for visualization of layered structures.
The RGB camera has crossed polarizing filter in order to minimize the surface effects of the the sample surface, due to water, etc.
Measurements are non destructive and performed without touching the sample surface.
The elements that can be detected range from Mg-U. The detection limits vary depending on choice of x-ray tube anode element.
The concentrations and all other data are available directly after the analysis, without need for calibration with other analyses.
Meeting your needs
The core scanner can house samples up to 185 centimeters long. Sample types include wet, split sediment cores in liners, drill cores, slabs, and other flat samples.
Very well established since many years
These scanners have been delivered since 2003, and is the market leading XRF scanner for wet sediments. You find installations at many renowned universities and research institutes across America, Europe, Oceania and Asia.
Itrax Core Scanner data are published in over 200 new scientific articles every year, making it the most used XRF scanner for scientific publishing by far.
Typical applications
The range applications include sedimentology, paleo-climatic research, sediment scanning in limnology, paleolimnology, oceanography, paleo-oceanography, and a range of other geological examinations to mention the most important ones. Itrax Core Scanner is well suited for scanning of split, wet sediments cores in liners, split or full circle drill cores, slabs, U channels, peat cores, cave stone slabs, and other flat samples . The good quantitative capacity also makes this instrument suitable for multi element analysis of powders in cups and pressed discs.
Data examples
This image shows an example of a x-ray radiographic image of a laminated sediment section, as recorded with Itrax Core Scanner. The height of the section is about 28 millimeter. Darker parts show higher density.
This example from Itrax Core
Scanner shows two element
profiles, one red and one black,
each displaying one Manganese
profile as recorded in two con-
secutive scans of the same core.
Each profile contains 3,000 mea-
surements with a spot size and
step of 0.2 millimeter, at a measuring time at each spot of 1 second. The average Manganese concentration range is ~0.02 - 0.2%. Applying longer measurement time improves the precision further, when needed. You cannot find another XRF scanner that offers this combination of speed and lateral resolution.
