We have developed an objective method for the determination of a herb extract's quality based on headspace measurements by proton-transfer-reaction mass spectrometry (PTR-MS); this quality was checked by a sensory analysis until now. This novel method enables the company ‘Bionorica’ to ensure that they are only selling high-quality products and therefore avoid complaints of the customer. The method could be also used for controlling and optimising the production process.
