Synergetic effect of laser and micro-fabricated glow discharge plasma in a new ion source for ambient mass spectrometry

Plasma‐based ambient mass spectrometry: Recent progress and applications

“…Furthermore, DBDI‐MS and LTP‐MS have also been coupled with different wavelength lasers for the analysis of nonvolatile chemicals (Bierstedt & Riedel, 2016; Gilbert‐Lopez et al, 2013), the distribution imaging of alkaloids in plant native tissues (Moreno‐Pedraza et al, 2019), and the improvement of LD LTP‐MS comparing with the conventional LTP‐MS (Gong et al, 2020). In a recent study, the detection limits of laser ablation MFGDP ion source (LA‐MFGDP) were reduced three orders of magnitude when comparing with MFGDP, which shows that the combination of laser ablation can significantly improve the analytical performance of MFGDP (He et al, 2021).…”
