title: 15N-labeled ionic probe attachment mass spectrometry of carbon clusters.
abstract: An ionization method that uses metal-complex-based ionization probes, malonic acid 3-[2,6-bis(4,4-dimethyloxazolin-2-yl)pyridin-4-yloxy]propyl ethyl ester (EM-TMpybox) and potassium N-{3-[2,6-bis(4,4-dimethyloxazolin-2-yl)pyridine-4-yloxy]propyl} aminoacetate (Sar-TMpybox), was developed for isotope ratio analysis and the effective ionization of unsubstituted carbon clusters. The preparation of Sar-TMpybox and EM-TMpybox and their applications in cold-spray ionization mass spectrometry are reported. A probe applicable to a substituted fullerene is also demonstrated.
