ESI; metal–ligand complexation; solution equilibria Abstract In the 20 years, since the introduction of electrospray mass spectrometry (ESI-MS), the use of this technique in various fields of inorganic, organometallic, and analytical chemistry has been steadily increasing. In this study, the applica...

Herein a fast and sensitive analytical method has been developed for the quantitative detection of eNO based on extractive electrospray ionization mass spectrometry (EESI-MS). Exhaled NO molecules selectively reacted with 2-phenyl-4, 4, 5, 5-tetramethylimidazoline-1-oxyl-3-oxide (PTIO) reagent ...
Mass spectrometry The spectra were measured using a high-resolution Thermo Scientific LTQ FT ULTRA mass spectrometer according to the previously described direct spray-from-tissue ionization method, otherwise known as NESI (Needle ElectroSpray Ionization)37. The tissue sample (about 2 mm3) was placed...
