Recent developments in environmental and liquid cells equipped with electron\ntransparent graphene windows have enabled traditional surface science\nspectromicroscopy tools, such as X-ray photoelectron spectroscopy (XPS),\nphotoemission electron microscopy (PEEM), and scanning electron microscopy\n(SEM) to be applied to study solid-liquid and liquid-gas interfaces. Here, we\nfocus on the experimental implementation of PEEM to probe electrified\ngraphene-liquid interfaces using electrolyte-filled microchannel arrays as a\nnew sample platform. We demonstrate the important methodological advantage of\nthese multi-sample arrays: they enable the combination of the wide field of\nview hyperspectral imaging capabilities from PEEM with the use of powerful data\nmining algorithms to reveal spectroscopic and temporal behaviors at the level\nof the individual microsample or the entire array ensemble\n
