Installation of an HPLC-DAD/APCI-MS and direct flame sampling/APCI-MS for fullerenes and PAH research. Initial report for instrumentation grant, Project period 1 August 1992--31 July 1994
Recently, the authors` research group at MIT discovered that both C{sub 60} and C{sub 70} fullerenes are produced in substantial amounts from benzene-oxygen-argon flames under certain conditions. Use of the PE/Sciex APCI-LC/MS will be crucial to the analysis of fullerene mixtures now being generated in flames in Department of energy sponsored research at MIT. The PE/Sciex APCI/LC-MS equipment consists of a high performance liquid chromatography (HPLC) with diode array spectrophotometric detector (DAD) interfaced to an atmospheric pressure ionizer with a single quadrupole mass spectrometer (MS) through a heated nebulizer. The interface between the HPLC and the MS is designed to minimize thermal input to the HPLC eluents and is of great importance for the intended application. Ionization occurs in a unique fashion at atmospheric pressure using a chemical ionization source (APCI). It will be used for the identification and quantification of flame-generated fullerenes and polycyclic aromatic hydrocarbons (PAH).
