Building a Bridge Between Ambient MS and LC‐MS by Non‐Exhaustive Microdesorption

open access: yesAngewandte Chemie International Edition, EarlyView.
A sequential analysis strategy was developed to integrate rapid ambient mass spectrometry (MS) screening with LC‐MS confirmation using a single solid‐phase microextraction (SPME) device. The approach involves an initial non‐exhaustive microdesorption for ambient MS screening, followed by a second desorption for LC‐MS confirmation of only the disputed ...
