2D elemental mapping at 50 nm spatial resolution provides information on the chemical composition and elemental distribution in the sample. Additional information can be obtained by simultaneously acquiring imaging data.
Spatially-resolved X-ray Absorption Near-Edge Structure provides information on the chemical speciation of the element of choice.
Multivariate cluster anaylsis revealing statistically-similar regions acording to their XANES spectra, can be performed by the cross-platform python package - Mantis.
Speciation maps can be calculated through fitting the absorption data from each pixel to the linear combination of the standard spectra, representing the ratio between the expected species (Gomez-Gonzalez et al. 2019 - ACS Nano, 2019, 13, 11049–11061).
X-ray ptychography imaging, which is a scanning coherent diffractive imaging technique, is now available at i14.
PtyREX, the reconstruction package for electrons and X-rays, was used for the processing and analysis of the ptychographic data. Each channel from the MERLIN detector was processed individually through 100 iterations of ePIE, with position correction and up-sampling.
