First proof of principle combination of hard x-ray ptychography with hyperspectralimaging at the I13-1 branch of DLS. Single shot discrimination of Ni versus Cu has beendemonstrated at 96 nm pixel size using K-edge subtraction, as well as measurement of theNi K-edge spectral profile from a single ptychographic acquisition.
