As an alternative to purge and trap (P&T) thermal desorption, in-tube extraction (ITEX) dynamic headspace offers excellent sensitivity for the analysis of volatiles and semi-volatile organics in solid, liquid and gas samples, without the cost and complexity of classical P&T systems.
ITEX dynamic headspace uses a gas-tight syringe to collect the headspace and a microtrap inside the syringe needle to efficiently extract and concentrate volatile and semi-volatile compounds. This is a syringe-only concept with no sample loops, transfer lines, or switching valves that could be contaminated. The five stages of the ITEX procedure are shown below.
