a Illustrative layout for Workflow 1 (for quantifying H & O pickup during transfer process). Overlay of the mass-to-charge spectra peaks with peak indexing for b 0–80 Da, c 23–47 Da, and d 49–80 Da for the APT datasets collected using laser pulsing along with corresponding 1D composition profiles of e H and f O and g bulk H-concentration of the entire reconstruction for the baseline, buffer chamber (30 min), and glovebox (30 min) experimental conditions of Workflow 1.
