Application Note: The Benefits of Direct Desorption and Sample Re-Collection Using the Markes TD-100 for the Aroma Profiling of Peppermint Tea
22 April 2015

This application note describes the determination of volatile organic components in peppermint tea using direct thermal desorption/extraction, followed by pre-concentration and GC–MS analysis. In addition to circumventing the need for sample preparation, the ability of Markes’ TD-100 thermal desorber to automatically re-collect vapor samples onto a sorbent-packed tube makes it possible to repeat the analysis under the same or different conditions.
