Analyzing odorants without artifacts—comparative study confirms established method as the gold standard
When analyzing odorants in food or its raw materials, the formation of artifacts can significantly distort the results. In a new comparative study, two researchers from the Leibniz-Institute for Food Systems Biology at the Technical University of Munich have shown that the injection method in gas chromatographic odorant analysis has a decisive influence on the formation of artifacts. On-column injection proved to be the gold standard, while solvent-free methods performed significantly worse.
