The XGT X-ray Fluorescence micro-analyzers combine the fast, non-destructive elemental analysis of energy dispersive X-ray Fluorescence (EDXRF) with the capability to pinpoint individual particles with diameters down to 10 µm in size. Automated sample scanning provides detailed images of element distribution, over areas as large as 10cm x 10cm.

There is no sample preparation or vacuum required – the object is simply placed in the sample chamber and analysed at normal atmospheric pressure. Fully integrated software controls sample movement, acquisition options and data analysis (including qualitative and quantitative analysis, and composite image generation). From when a sample is put in the chamber, just a few seconds are needed until an acquisition is started, aided by intuitive “point and click” selection of the analysis position.

The sample is visualised with coaxial geometry, so that parallax errors are removed. You have absolute confidence that where you see is where you sample.

Two X-ray guide tubes are provided in the instrument, allowing the user to simply switch between a micro and macro beams, so that a range of experiments can be accommodated. The high intensity beam delivered by these guide tubes ensures that acquisition times are kept to a minimum. The mono-capillary design of these guide tubes are ideally suited for high intensity element imaging, even of samples which are not perfectly flat.

XRF mapped images are easily obtained through automated sample scanning, and the provision of a second detector beneath the sample enables simultaneous acquisition of X-ray transmission images. The additional structural information provided by this technology is extremely useful for locating regions of interest, or interrogating a sample’s internal structure.
