A needle-type extraction device is one of the promising sample preparation devices for gas chromatographic (GC) analysis various organic compounds. The most remarkable advantage this a simple and rapid desorption analytes by direct insertion an needle into conventional GC injection port. In review, fundamental aspects its applications determination trace compounds, especially volatile compounds (VOCs), in several matrices are described.
A purge-and-trap method using a needle-type extraction device and gas chromatography-barrier discharge ionization detector for the analysis of formic (FA) acetic acids (AA) in aqueous samples is presented. An activated carbon-based adsorbent, Carboxen 1000, was employed as medium device. The sampling time 5 min collecting headspace glass vial, including 10 mL an sample. detection limits FA AA with volume 100 were 3.3 2.0 mg L-1, respectively. Since proposed based on collection, it suitable...
The musty-odor compounds (MOCs) 2-methylisoborneol (2-MIB) and geosmin in water samples were determined by a purge-and-trap method using needle-type extraction device followed gas chromatography–mass spectrometry. For the of these compounds, triple-layer-type needle containing divinylbenzene activated carbon particles as particulate media was introduced. Several experimental parameters, including sample temperature during extraction, addition sodium chloride, desorption conditions,...
