The XRF spectrometer measures the individual component wavelengths of the fluorescent emission produced by a sample when irradiated with X-rays.

Precilab uses the XGT-5000 from HORIBA for XRF analyses.
The XGT-5000 is an Energy Dispersive (ED)-XRF and makes use of the fact that the pulse height of the detector signal is proportional to the X-ray photon energy.

This instrument can provide not only qualitative but semi-quantitative and quantitative analysis for elements from Sodium to Uranium. Furthermore, accuracy of the results is greatly enhanced with the “Multi-point quantitative analysis”.

The XGT Series is named for the specific feature in its construction called an X-Ray Guide Tube. The guide tube allows for better alignment of the X-Ray source and the optical CCD Camera. The result is a more integrated combination of optical microscope observation with X-Ray analysis. Furthermore, the XGT-5000 can be used with two different sizes of the source X-Ray beam; 1.2mm and 10µm. The small X-Ray beam of 10µm allows a high spatial resolution over smaller areas; whereas the 1.2mm x-ray beam can provide faster analysis or mapping over larger areas. The larger beam size is also ideally suited for spot testing of specific surface sites with sensitivity down to the low ppm level, depending on the element.
