Analysis of Trichloroanisole in Wine and Cork using a Purge and Trap Multimatrix Autosampler
Abstract Due to its low odor threshold, 2,4,6-trichloroanisole (TCA), the compound responsible for “cork taint”, requires extremely sensitive analysis. TCA is a fungal metabolite of 2,4,6-trichlorophenol (TCP). Even minute contamination can cause issues with regards to taste. This study will demonstrate a purge and trap method for analyzing wine and cork samples at the ...

Comparison of BTEXS in Olive Oils by Static and Dynamic HT3 Headspace
Abstract Purge and trap concentration is a technique that is used for the analysis of Volatile Organic Compounds (VOCs). The major component of any purge and trap system is the analytical trap. This trap is responsible for retaining the VOCs during the purge cycle and then releasing them upon heating and transfer to the GC/MS for separation and detection. While most standard methods define the ...
