 abstract = {Significant developments in the field of ambient desorption/ionization mass spectrometry (MS) have led to high-throughput direct analysis and imaging capabilities. However, advances in coupling ambient ionization techniques with standalone drift tube ion mobility spectrometry (DTIMS) have been comparatively slower, despite the attractive ruggedness and simplicity of IMS. In this study, we have developed and characterized a laser ablation/desorption electrospray ionization (LADESI) DTIMS platform, and applied it to the detection of active pharmaceutical ingredients (APIs) in antimalarial tablets collected in developing countries. The overarching goal of this work was to perform an initial evaluation of LADESI DTIMS as a technique with the potential for constituting the core of a portable drug quality-testing platform. The set-up consisted of an IR laser for desorption and an electrospray ionizer for capturing the ablated plume coupled to a high-resolution monolithic resistive glass drift tube ion mobility spectrometer. For more confident API identification, tablet extracts were also investigated via electrospray IM MS to correlate LADESI DTIMS reduced mobility (K(0)) values to m/z values. Overall, it was found that the IR LADESI DTIMS platform provided distinct ion mobility spectral fingerprints that could be used to detect the presence of the expected APIs, helping to distinguish counterfeit drugs from their genuine counterparts.},
