Hi, On the beamline i23 at Diamond, we can reach the Ca and K edges hence we can easily calculate anomalous difference Fourier maps to identify these elements experimentally. https://www.diamond.ac.uk/Instruments/Mx/I23.html Cheers, Kamel From: CCP4 bulletin board On Behalf Of Jan Dohnalek Sent

Re: [ccp4bb] Elemental Analysis

Dear Andy, We can easily reach the Ca absorption edge on I23 (Diamond long wavelength beamline), so we can tell you if you have calcium in your crystal but also its location. Have a look at the beamline webpage: https://www.diamond.ac.uk/Instruments/Mx/I23.html Cheers, Kamel
