Itrax Multiscanner


The Itrax Multiscanner combines density measurements, XRF multi-element analysis and RGB image. It is developed for analysis of wood, speleothem and other small, flat samples. This high capacity instrument scans over the samples with a fine x-ray beam to provide a density image. When the bulk is well known, like in wood, a calibrated and precise density value is available. The density information is recorded directly into a digital medium, so all work is done through the computer without use of film, etc. involved.

The Multiscanner utilizes soft x-rays of high intensity, and sample scanning is therefore quick, and data accurate. The lateral resolution is high enough to allow for fine determination of parameters like year ring width and maximum density in late wood. The whole analytical procedure from setting parameters to working on the data is computer based.

A sample holder with room for several samples makes unattended multi sample scanning possible. The XRF allows for analysis of a range of elements from Mg and heavier. The elements that are usually detected in wood include Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Fe, Ni, Cu, Zn, As, Rb and Sr. Many more elements can be detected depending on concentration in the wood, and time for analysis.
