Fast Mass Microscopy: Mass Spectrometry Imaging of a Gigapixel Image in 34 Minutes

open access: yes, 2022
[Image: see text] Mass spectrometry imaging (MSI) maps the spatial distributions of chemicals on surfaces. MSI requires improvements in throughput and spatial resolution, and often one is compromised for the other. In microprobe-mode MSI, improvements in
