Generating Electrospray Ionization on Ballpoint Tips

Analytical Chemistry, 2016
In this study, we report a simple and economical ballpoint electrospray ionization mass spectrometry (BP-ESI-MS) technique. This combines a small ballpoint tip with a syringe pump for the direct loading and ionization of various samples in different phases (including solution, semisolid, and solid) and allows for additional applications in surface ...

Microfabrication of Polydimethylsiloxane Electrospray Ionization Emitters

Journal of Chromatography A, 2001
Microfabricated polydimethylsiloxane (PDMS) emitters for electrospray ionization mass spectrometry (ESI-MS) were implemented as tips along the edge of the PDMS device by three methods which utilize soft lithography processes. These microfabrication methods for producing PDMS emitters as an integral part of a microfluidic device will facilitate ...

On the Mechanism of Extractive Electrospray Ionization

Analytical Chemistry, 2010
Extractive electrospray ionization (EESI) is a powerful ambient ionization technique that can provide comprehensive mass spectrometric (MS) information on aerosols, complex liquids, or suspensions without any sample pretreatment. An understanding of the EESI mechanism is critical for defining its range of application, the advantages, and limitations of

Unraveling the Mechanism of Electrospray Ionization

Analytical Chemistry, 2012
Electrospray ionization (ESI) generates intact gas-phase ions from analytes in solution for mass spectrometric investigations. ESI can proceed via different mechanisms. Low molecular weight analytes follow the ion evaporation model (IEM), whereas the charged residue model (CRM) applies to large globular species.

Ion suppression effect in desorption electrospray ionization and electrospray ionization mass spectrometry

Rapid Communications in Mass Spectrometry, 2017
Rationale Although it is claimed that desorption electrospray ionization (DESI) causes less ion suppression effects than electrospray ionization (ESI), a related investigation with quantification measurement of ion suppression effects is absent.

Probe Electrospray Ionization

2014
Probe electrospray ionization (PESI) is an electrospray-based atmospheric-pressure surface sampling and ionization technique for mass spectrometry that uses a solid needle instead of a capillary. While ionization occurs in a fashion similar to that involved in electrospray ionization, the novel aspect of PESI is discontinuous sampling.
