Univocal Identification of Flavor and Fragrance Compounds Using GC-MS (TOF) / Condensed Phase FTIR with an Extensive Library
To obtain a univocal identification we need three independent pieces of analytical information. Flavor and Fragrance components are usually separated by gas chromatography and identified with MS spectral comparison and linear retention indices (LRI).
However, diastereomeric or positional isomers can present identical retention behavior and MS spectra, and can cause misidentification. The development of a unique condensed-phase FTIR provides the solution – a simple post-column split combines it with a GC-MS instrument, using the GC to separate the components and MS (TOF) and FTIR spectrometers to give structural elucidation in a single analysis.
