FEI Quanta 200 Environmental Scanning Electron Microscope
The FEI Quanta 200 is scheduled to be installed in early November 2015. The Quanta200 can be operated in regular high-vacuum, low-vacuum and full Environmental ESEM modes for imaging many varieties of samples. It will be equipped with iXRF software/hardware and an e2v SSD EDS detector which can measure >300,000 x-ray counts/second.
As part of sample preparation, samples are coated to improve conductivity with Au/Pt or Ir. These can often be seen in the XRF spectrum and are also often misidentified. Check out the X-Ray data booklet to find X-ray emission lines.
