The PW2400 was the last instrument from the first generation in PML. It was a state-of-the-art instrument that allowed us to acquire more precise data on smaller samples. This means that we were able to analyze smaller samples (between >5 to <10 mm) with greater precision non-destructively. The instrument was equipped with a 102 sample changer. About thirty samples were able to be analyzed in under 3.5 hours. Non-destructive analysis is facilitated by the SuperQ software designed by Philips allowing for ratioing to the Compton scatter similar to EDXRF analysis.
The new spectrometer is a PANalytical AXIOS-Advanced WDXRF spectrometer and is fitted with an SST-MAX X-ray sourcewith a 4kW output and can be operated at 160mA. The resulting high X-ray flux enables high sensitivity and low detection limits for light elements. The AXIOS can measure elements over wide dynamic concentration ranges and include all the elements between Be and U in the periodic table. The AXIOS uses SuperQ software for standard-based analysis and has a standard-less software module called OMNIAN capable of giving the complete composition and quantification of most types of unknown materials.
