Paper Abstract

The first demonstration is described of identifiable infrared (IR) spectra obtained from volatile buffer mobile phase using Monodisperse Aerosol Generator Interface Combining Liquid Chromatography with Fourier transform infrared (MAGIC-LC/FT-IR) spectrometry. Ammonium acetate, a volatile buffer, was used to buffer an 80:20 acetonitrile:water mobile phase to pH 5.0. Caffeine was deposited from this buffered mobile phase on a KBr window and the resulting spectrum compared favorably with a reference caffeine spectrum. The caffeine reference spectrum was obtained by depositing caffeine from a 100 percent water mobile phase.
