Plasma-Spray Ionization (PLASI): A Multimodal Atmospheric Pressure Ion Source for Liquid Stream Analysis

Abstract: A new ion generation method, named plasma-spray ionization (PLASI) for direct analysis of liquid streams, such as in continuous infusion experiments or liquid chromatography (LC), is reported. PLASI addresses many of the analytical limitations of electrospray ionization (ESI) and has potential for real time process stream analysis and reaction monitoring under atmospheric conditions in non-ESI friendly scenarios. In PLASI-mass spectrometry (MS), the liquid stream is pneumatically nebulized and partially charge… Show more

“…The enrichment of SASs in the SML occurs predominantly via advective and diffusive transport at low wind speeds or bubble scavenging at moderate to high wind speeds (Wurl et al, 2011). When transferred to the atmosphere, OM with surfactant properties, ubiquitously present in atmospheric aerosol particles, has the potential to affect the cloud droplet formation ability of these particles (e.g., Kroflič et al, 2018).…”

“…Thermallydesorbed analytes having typically MW<1000, are ionized following atmospheric pressure chemical ionization-like pathways (Cody et al, 2005;Song et al, 2009a;Song et al, 2009b;McEwen and Larsen, 2009). An important advantage of DART compared to electrospray ionization for seawater analysis is that it is less affected by high salt levels (Kaylor et al, 2014;Tang et al, 2004), avoiding desalinization processes that may lead to sample alteration.…”

“…Additionally, a multimodal atmospheric pressure ion source for liquid stream analysis has recently been developed (Kaylor et al, ). This source, named PLASI (plasma‐spray ionization), can be used in either plasma or ESI modes by toggling the sprayer inlet capillary potential difference between the low (1–1.2 kV) and high (3.5 kV) settings.…”
