Probing Cyanocuprates by Electrospray Ionization Mass Spectrometry [PDF]
Organometallics, 2010 Solutions of CuCN/(RLi)n (n = 0.5, 0.8, 1.0, and 2.0 and R = Me, Et, nBu, sBu, tBu, and Ph) in tetrahydrofuran are analyzed by electrospray ionization mass spectrometry. In all cases, organocuprate anions are observed, whose exact nature depends on the reagent stoichiometry.

Synchronized dual-polarity electrospray ionization mass spectrometry [PDF]
Journal of the American Society for Mass Spectrometry, 2009 This work describes the synchronized dual-polarity (DP) electrospray ionization (ESI) method and demonstrates the first DP ESI mass spectra obtained using two mass spectrometers. Stable double Taylor cones were produced by applying two counter electric voltages with opposite polarities to one electrosprayer.

Electrospray Post-Ionization Mass Spectrometry of Electrosurgical Aerosols [PDF]
Journal of the American Society for Mass Spectrometry, 2011 The feasibility of electrospray (ES) ionization of aerosols generated by electrosurgical disintegration methods was investigated. Although electrosurgery itself was demonstrated to produce gaseous ions, post-ionization methods were implemented to enhance the ion yield, especially in those cases when the ion current produced by the applied ...

Electrospray ionization mass spectrometry with wooden tips: A review
Analytica Chimica Acta, 2022 Electrospray ionization (ESI) is a powerful ionization technique in mass spectrometry (MS). There has been an increasing interest for the new development of ESI technique to extend its applications. ESI-MS with wooden tips (wooden-tip ESI-MS), an ESI technique invented in 2011, enabled not only new applications but also new insights into the ESI ...
