Reduction of metal adducts in oligonucleotide mass spectra in ion-pair reversed-phase chromatography/mass spectrometry analysis.

Rapid communications in mass spectrometry : RCM

Birdsall RE, Gilar M, Shion H, Yu YQ, Chen W.
PMID: 28328039
Rapid Commun Mass Spectrom. 2016 Jul 30;30(14):1667-1679. doi: 10.1002/rcm.7596.

RATIONALE: Electrospray ionization mass spectrometry (ESI-MS)-based techniques commonly used in oligonucleotide analyses are known to be sensitive to alkali metal adduct formation. Adducts directly impact the sensitivity of MS-based analyses as the available charge is distributed across the parent...
