The flavor fingerprint of Eucommia ulmoides Oliv. bark (EUb) and its fermentation product were investigated, and volatile compounds were analyzed using headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS) combined with partial least squares discrimination analysis (PLS-DA).

The handheld headspace gas analyzers within the PAC CHECK 300 series carry out precise oxygen, carbon dioxide and carbon monoxide analysis. This model is among the fastest and most accurate CO2, O2 and CO gas analyzers in the market. The oxygen, carbon dioxide and carbon monoxide analyzer conduct fast and accurate measurements of MAP products

Basic principles of headspace analysis. A headspace sample is usually prepared in a vial containing the sample, the dilution solvent, a matrix modifier and the headspace. Volatile components from complex sample mixtures can be extracted from non-volatile sample components and isolated in the headspace or gas portion of a sample vial.
