Letter: radical ion and protonated molecule formation with retinal in electrospray and nanospray.
This paper reports a preliminary study of the nanospray ionisation mass spectrometry analyses of retinoic acid and retinal. The results are compared and contrasted to the results normally observed with electrospray ionisation. A significant difference in behaviour was observed for the balance between radical ion formation and protonated molecule formation for retinal. The results suggest that the influence of the very different ionisation conditions present in nanospray is very important in determining how ionisation is achieved and has potentially wide ranging applications in the fields of mass spectral analysis of biological and medical extracts.
