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 ...

Electrospray ionization mass spectrometry of metalloporphyrins

Journal of Mass Spectrometry, 1998
The magnesium, nickel, copper, zinc and vanadium metalloporphyrins from octaethylporphyrin, etioporphyrin I and tetraphenylporphyrin were characterized using electrospray ionization mass spectrometry (ESI-MS). The ion abundance of each of the porphyrins present in binary mixtures was monitored as a function of the porphyrin concentration and is ...

Secondary Electrospray Ionization

2014
This chapter details the technique called extractive electrospray ionization (EESI) and describes its state-of-the-art developmental, mechanical and experimental aspects and shows its most important applications. EESI is a sensitive, matrix-tolerant secondary electrospray ionization technique, which is in the focus of ongoing investigations.

Electrospray Laser Desorption Ionization

2019
Electrospray laser desorption ionization (ELDI) combines the features of both electrospray ionization and laser desorption. It allows direct, sensitive, and rapid analyses of chemical compounds on the sample surfaces. Chemical and biological compounds dissolved in polar and nonpolar solvents can also be characterized directly by ELDI-mass spectrometry (
