- Abstract
The article discusses a study which detected a series of unexpected [M--H]+ ions from cyclopenta[b]indoles by electrospray ionization-mass spectrometry (ESI-MS), which were further studied using collision-induced dissociation (CID) MS/MS. The study used high performance liquid chromatography grade methanol, formic acid, and sodium hydrate, and the mixture of formic acid and sodium hydrate was used as the mass calibration standard.
