2nd EDS Detector!

Last week saw the visit of Bruker to fit our second EDS detector (the xFlash 6|60) and upgrade the analytical software. The additional detector allows Petrolab to acquire spectra simultaneously on two detectors reducing the time required to reach an acceptable level of counts for mineral identification. There are further added benefits in improving edge effect analysis and allowing more versatile analysis options on samples with topography. Finally, the software upgrade from Esprit 1.9 to 2.1 for the Bruker software brings added power and utility for element mapping and quantification. All-in-all the upgrades are an exciting development for Petrolab allowing us to increase sample throughput, analyse a wider range of sample morphologies and with greater analytical versatility on point & shoot job requirements.  ... read more
