Abstract excerpt
A rapid on-line desalting method utilizing ion-pair reversed-phase high-performance liquid chromatography (IP-RP-HPLC) was employed in tandem with negative electrospray ionization mass spectrometry (ESI-MS) for the routine analysis of nucleic acids. Desalting was performed on a short 10 x 2.1 mm guard column packed with 3.5 microm C(18) sorbent. The HPLC system was connected in-line to an orthogonal ESI-TOF mass...
