This is the duel STEM-EDS and EELS of Iron Biomineralization Patterns in a Denitrifying As(III)-Oxidizing Bacterium

Showing both regions of high As and low As

Taken on FEI Titan G2 ChemiSTEM running at 200kV using a 180 pA beam current. This microscope was also fitted with a SuperX EDS detector system and EELS via Gitan GIF Quantum ER EELS spectrometer in which both Duel EELS and EDS data were collected simultaneously using the Gitan Digital Micrograph software
