Electrospray ionization mass spectrometry of ginsenosides

Journal of Mass Spectrometry, 2002
AbstractGinsenosides Rb1, Rb2, Rc, Rd, Re, Rf, Rg1, Rg2 and F11 were studied systematically by electrospray ionization mass spectrometry in positive‐ and negative‐ion modes with a mobile‐phase additive, ammonium acetate. In general, ion sensitivities for the ginsenosides were greater in the negative‐ion mode, but more structural information on the ...

Electrospray Ionization Mass Spectrometry of Oligonucleotides

Current Protocols in Nucleic Acid Chemistry, 2008
AbstractBecause of the high molecular weights and thermal lability of biomolecules such as nucleic acids and protein, they can be difficult to analyze by mass spectrometry. Such analyses require a “soft” ionization method that is capable of generating intact molecular ions.

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 ...

Electrospray Ionization Ion Mobility Mass Spectrometry

Critical Reviews in Analytical Chemistry, 2021
Electrospray ionization ion mobility mass spectrometry (ESI-IMS-MS) is a rapidly progressing analytical technique for the examination of complex compounds in the gas phase. ESI-IMS-MS separates isomers, provides structural information, and quantitatively identifies peptides, lipids, carbohydrates, polymers, and metabolites in biological samples.
