Abstract :

Gas sampling techniques, especially for the enrichment and separation of trace gases from complicated matrix still remain one of the weak spots in analytical chemistry nowadays due to gas strong volatility, compared with liquid and solid sample.Efficient gas sampling techniques should possess the highest extraction capacity and selectivity and can be conveniently coupled with sequent analytical instruments. The core of developing efficient gas sampling techniques lies in the development of new enrichment media with higher extraction capacity and selectivity. In our previous reports, a series of novel enrichment media, including one-dimensional nano-arrayed, conjugated doping and Metal Organic Frame (MOF)-based coatings were developed, which mainly focused on the improvement of sampling capacity and selectivity for trace target gases from real samples with complicated matrices. The fabrication formats of these novel enrichment media, mainly involved sorbent tube, headspace stir bar and Solid-Phase MicroExtraction (SPME) coatings coupling with the consequent analytical instruments. These novels trace gas enrichment media have been successfully applied for the enrichment and analysis of trace target volatiles from food, environmental and biological samples.
