Analysis of Oligonucleotides by Electrospray Ionization Mass Spectrometry [PDF]
Current Protocols in Nucleic Acid Chemistry, 2000 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.

Desorption Electrospray Ionization-Mass Spectrometry of Proteins [PDF]
Analytical Chemistry, 2007 Desorption electrospray ionization-mass spectrometry (DESI-MS) was evaluated for the detection of proteins ranging in molecular mass from 12 to 66 kDa. Proteins were uniformly deposited on a solid surface without pretreatment and analyzed with a DESI source coupled to a quadrupole ion trap mass spectrometer.

Ionization and transmission efficiency in an electrospray ionization—mass spectrometry interface [PDF]
Journal of the American Society for Mass Spectrometry, 2007 The ionization and transmission efficiencies of an electrospray ionization (ESI) interface were investigated to advance the understanding of how these factors affect mass spectrometry (MS) sensitivity. In addition, the effects of the ES emitter distance to the inlet, solution flow rate, and inlet temperature were characterized.
