Dehydration of 2-methylisoborneol to 2-methyl-2-bornene in the Trace Analysis of Taste-Odorants in Water by Purge-and-Trap Sampling with Gas Chromatography (GC) -Mass Selective (MS) Detection

A “salt-free”, automated purge-and-trap sampling method, with gas chromatographic-mass spectrometric detection for simultaneous detection of 2-methylisoborneol (2-MIB) and geosmin (GSM) was developed. The preliminary procedure involved purging a 25 mL water sample, at 80°C for 11 min, with helium gas, and trapping onto a Tenax sorbent.
