Notes:
A mixture of four squalestatins was separated anil characterized by gradient packed capillary liquid chromatography combined with electrospray collision-induced dissociation mass spectrometry (ESI/CID/MS). Negative-ion ESI was found to afford spectra typified by strong pseudo-molecular ions but providing little structural information. Structural information was obtained using an ion-focusing RF-only octapole lens to provide conditions for CID. The new method showed improvements in sensitivity when compared to existing thermospray and dynamic liquid secondary-ion mass spectrometry methods.
