Screening of Tropical Fruit Volatile Compounds Using Solid-Phase Microextraction (SPME) Fibers and Internally Cooled SPME Fiber

Journal of Agricultural and Food Chemistry, 2006
In this study, the optimization and comparison of an internally cooled fiber [cold fiber with polydimethylsiloxane (PDMS) loading] and several commercial solid-phase microextraction (SPME) fibers for the extraction of volatile compounds from tropical fruits were performed.

Microextraction en phase solide (SPME)

Techniques d'analyse, 2019
La preparation d’echantillon est difficile surtout lorsque le compose d’interet est present en faible quantite dans une matrice complexe. De nombreuses methodes existent pour extraire et preconcentrer les analytes mais elles sont souvent longues ou consommatrices de solvant. La microextraction en phase solide ne presente pas tous ces inconvenients.

Field air analysis with SPME device

Analytica Chimica Acta, 1999
Solid-phase microextraction (SPME) devices were used for a wide scope of air-monitoring including field sampling and analysis of volatile organic compounds (VOCs), formaldehyde, and particulate matter (PM) in air. Grab (instantaneous) and time-weighted average (TWA) sampling were accomplished using exposed and retracted SPME fibers, respectively ...

Microestrazione in fase solida (SPME)

2014
La microestrazione in fase solida (SPME, solid-phase microextraction), sviluppata da Pawliszyn e collaboratori nel 1989 (Arthur, Pawliszyn, 1990), e una tecnica che utilizza una fibra di silice fusa, rivestita esternamente da una piccola quantita di fase stazionaria adsorbente, che viene esposta al campione.
