Enhanced aroma-profiling of peppermint tea using direct desorption TD–GC–MS with sample re-collection
Application Note 111
This application note describes the determination of volatile organic components in dried peppermint tea leaves using quick and convenient direct desorption of a small sample, followed by thermal desorption (TD)–GC–MS analysis with electron ionisation.
Automated re-collection of the split flow onto a sorbent-packed tube is then used to re-analyse the same vapour sample using positive chemical ionisation, for enhanced confidence in the identification of key compounds.
