Outline of Final Research Achievements |
Atmospheric pressure ion source for online coupling of liquid chromatography (LC) and mass spectrometry (MS) was developed using an infrared laser and a porous metal thin disk called frit. Peptides dissolved in water or mixture of water and acetonitrile were successfully ionized and analyzed with MS by tuning the laser wavelength to the absorption peak of the solvent. Moreover, online LC/MS of a mixture of peptides was succeeded.
