Atmospheric pressure photoionization mass spectrometry.
Atmospheric pressure photoionization (APPI) is the last arrival in the family of atmospheric pressure ionization (API) methods to couple mass spectrometry (MS) to liquid-phase separation techniques. The basic idea was to further extend the fields of application of liquid chromatography (LC)-MS to those molecules that are not, or are poorly amenable, to electrospray (ESI) or APCI. The present re...
متن کاملBreath Analysis Using Photoionization Mass Spectrometry
REMPI (Resonantly Enhanced Multi Photon Ionization) is an ultra-sensitive analytical technique based on the unique combination of laser spectroscopy and mass spectrometry that can rapidly identify and quantify vapor-phase constituents present at part per trillion levels. We have used this method to examine human breath samples for biomarkers of infection. Based on the observed results, we estim...
متن کاملInfrared laser ablation atmospheric pressure photoionization mass spectrometry.
In this paper we introduce laser ablation atmospheric pressure photoionization (LAAPPI), a novel atmospheric pressure ion source for mass spectrometry. In LAAPPI the analytes are ablated from water-rich solid samples or from aqueous solutions with an infrared (IR) laser running at 2.94 μm wavelength. Approximately 12 mm above the sample surface, the ablation plume is intercepted with an orthogo...
متن کاملPhotoionization efficiency spectrum and ionization energy of HSO studied by discharge flow-photoionization mass spectrometry
The photoionization efficiency ~PIE! spectrum of HSO was measured in the spectral range ~107– 130! nm by means of a discharge flow and a photoionization mass spectrometer coupled to a synchrotron as the radiation source. HSO radicals were generated by reacting O atoms with various organothiol compounds, C2H5SH, 2-C3H7SH, or HSC2H4SH, in the flow tube. The ionization energy of HSO was determined...
