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.
