A study on electrospray mass spectrometry of fullerenol C 60 (OH) 24
Full characterization of fullerenol C 60 (OH) 24 by HPLC ESI-MS in negative and positive ionization modes was achieved. Fragmentor voltage and capillary voltage were optimized in order to obtain a good signal stability and the best peak intensity distribution for the fullerenol C 60 (OH) 24 in both...
