Unique Solution for Reliable Hot Sample XRF Analysis Launched

Oxford Instruments (UK) has launched a unique solution for reliable X-ray fluorescence (XRF) analysis of hot samples, for use with their range of X-MET8000 series handheld XRF analysers. The HERO heat resistant protective window allows hot samples of up to 400ºC to be directly analysed for alloying elements including light elements such as silicon.

Positive Material Identification (PMI) inspection sometimes requires the testing of in-service components such as pipes, reaction vessels, etc. that are at high temperatures. When testing hot samples using the X-MET8000, the operator simply swaps the analyser’s normal Prolene window for the HERO heat resistant window. Unlike other solutions available, there is no need for special spacers, shields or tilting techniques, which may have a detrimental effect on the accuracy of the results, especially for light elements. The use of the new window allows the operator to carry out in-service testing, therefore minimising downtime.

Christelle Petiot, Product Manager, Oxford Instruments, said “This unique solution truly simplifies the task for operators wanting to test in-service, high temperature components, whilst retaining the analyser’s excellent performance. Unlike other solutions currently on the market, there is no need for additional accessories or special measuring techniques that may cause results to vary from one user to another. With the use of the HERO window, operators also retain the capability of measuring light elements, which is critical in the testing of low alloy steels and other alloys.” 

The X-MET8000 series of field portable analysers are fitted with a large-area silicon drift detector (SDD) and high performance X-ray tube, delivering the exceptional speed and superior performance needed for the measurement of trace alloying elements. The X-MET8000 is manufactured with a rugged enclosure and its IP54 rating ensures durability and low cost of ownership making it ideal for use outside. Its large heat sink provides the most efficient heat dissipation ensuring stability and reliability, even in hot environments. Compact and lightweight at only 1.5kg including the battery, the X-MET8000 is fully portable for true on-site analysis.

The X-MET8000 range comprises three models of analysers designed to cover all analysis needs and budgets. The entry level, X-MET8000 Smart analyser is ideal for the routine identification and analysis of common alloys. The mid-range X-MET8000 Optimum model is optimised for high speed grade identification and analysis, from aluminiums to high temperature alloys, to steels etc. The top of the range X-MET8000 Expert provides the ultimate performance for the testing of the widest variety of alloys; with superior light elements (Mg, Al, Si, P and S), tramp and residual elements analysis.
