Combinatorial electrochemistry has great promise for accelerated reaction screening, organic synthesis, and catalysis. Recently, we described a new high-throughput platform, colloquially named "Legion". Legion fits the footprint of 96-well microtiter plate with simultaneous individual control over all 96 electrochemical cells. Here, demonstrate versatility when coupled mass spectrometry (MS) electrosynthetic product screening quantitation. Electrosynthesis benzophenone azine was selected as model arrayed optimized using combination nanoelectrospray ionization MS. The synthesis analysis via MS proves compelling strategy accelerating discovery optimization in electro-organic synthesis.

Catalyst dissolution is one of the key challenges in achieving long‐term performance proton exchange membrane water electrolysis with low iridium loading. However, most dissolved catalyst remains catalyst‐coated membrane, inaccessible for operando quantification. While simpler aqueous model systems improve mechanistic understanding, rates are significantly overestimated compared to device level. To bridge this gap, herein, an electrochemical half‐cell setup that mimics anode layer environment enable operation at relevant current densities (>1 ) presented. Dissolved species transported through porous transport or separately detected by coupling inductively coupled plasma‐mass spectrometry. The results demonstrate a strong preference (99.9%) and decrease stability factor 10 high densities. Discrepancies so far reported findings from full‐cell experiments highlight lack understanding transportation different systems. presented method offers unique insights which will help study optimize means various manufacturing parameters ultimately layers electrolysis.
