Hello all, We have had the good fortune to receive positive news about funding for a new powder XRD. We plan to operate this primarily with a Cu anode, but we do have undergraduate students who periodically have projects that require analysis of Fe-rich and Mn-rich minerals. The manufacturer does not currently have a Mo anode available (backordered for months, most likely) but does have a Co anode available. What are the advantages/ disadvantages of a Co source relative to a Mo source? Many thanks for your responses!
