Visible and Near-infrared Laser Desorption Ionization Mass Spectrometry Using Single Wall Carbon Nanotubes

We demonstrated detection of PEG 1000 on a surface of si single wall carbon nanotubes (SWCNTs) for surface-assisted laser desorption ionization mass spectrometry (SALDI-MS) by irradiating laser pulses with wavelengths of 532 and 1064 nm. We succeeded in observation of molecule-related ion of a coronene with no fragmentation in visible SALDI-MS measurements.
