Itrax XRF Core Scanner


When you want the best

Itrax XRF Core scanner is the flagship among XRF scanners, with several unique features, and with world class performance in terms of speed of analysis, speed/performance ratio, detection limits, data reproducibility, and documented ability to make good estimates of the concentrations of the elements found in samples.

Today we have delivered more than 50 instruments to leading universities and research institutes world wide. The number of scientific articles containing Itrax Core Scanner data that are published grows for every year and is now around 200 per year, indicating the significance of this instrument.

Useful combination of techniques

Itrax Core Scanner combines XRF scanning, x-ray radiographic images, high quality optical images and magnetic susceptibility measurements. Having these different measurements in one instrument means matching of the positions of the different measurements.

The large amount of reliable information that can be retrieved from a sample in a few minutes or hours has made this instrument a central resource in many laboratories.


Itrax is well suited for scanning of wet sediment samples resting in liners, as well as drill cores with circular or split cross section, since measurements are done without touching the sample surface.

The high speed leaves an option to scan wet sediments without having to apply a foil, thereby avoiding a possible formation of a water film under the foil, which may affect the data.

Drill core surfaces can also be scanned with good results, since Itrax does not need good contact in order to get reliable data.

Power to determine

Each measurement is performed close to the sample surface, without touching it. Itrax keeps track of the topography at every point along the sample, and performs the measurements at the right height above the surface, also when the surface is somewhat uneven. This feature saves a lot of time, without need to move the measuring device up and down to touch the surface at each point.


Good reproducibility is something that you can always expect with Itrax. Already when applying short time for analysis at each point, you get high quality data, One example of this is shown here.

This diagram shows in the red and black graphs two element profiles, each displaying the same distribution of Manganese in a sediment core, as recorded with Itrax Core Scanner in two consecutive, continuous scans. Each profile contains 1,000 measurements with 0.2 millimeter increments. Each step was measured during one second only. The concentration of Manganese varies within the range of ~0.02-0.2%.

High speed scanning

The scanning step size is variable, allowing for quick overview scans as well as detailed high resolution scans. Itrax has a very useful feature in that it does not lose speed as the step size is decreased. This is an in-house Cox Analytical construction and a really time saving feature for high resolution scanning. The smaller the steps, the more time saved, making a big difference at steps of one millimeter or less per point.

Scanning ove sample surface

Itrax Core Scanner is non destructive and does not touch the sample surface during analysis. This saves a lot of scan overhead time, makes this instrument good at handling sample cracks, and allows for good analyses also of the rounded surface of drill cores.


The software has a graphical user interface which is easy to handle. One of many useful software features is the analytical quality feedback from the software, giving the user an indication of the data quality, point by point.

The software for element quantification delivers robust quantitative data estimates for all elements, in good accordance with other techniques and based on calibration with certified reference standards and Fundamental Parameter Technique.
