Abstract ▼ AI-Helper

A Solid-phase micro extraction(SPME) was evaluated as a tool for headspace sampling of tobacco samples. Several experimental parameters (sampling temperature, pH, and type of SPME fibers) were optimized to improve sampling efficiency in two aspects ; maximum adsorption and selective adsorption of volatile organic acids onto SPME fibers. Among four types of SPME fibers such as PDMS(Polydimethylsiloxane), PA(Polyacrylate), Car/PDMS (Carboxen/Polydimethylsiioxane) and PDMS/DVB(Polydimethylsiioxane/Divinylbenzene) which were investigated to determine the selectivity and adsorption efficiency. A variety of tobacco samples such as flue cured, burley and oriental were used in this study. The effect of these parameters was often dominated by the physical and chemical nature (volatility, polarity) of target compounds. This method allowed us to make important improvements in selectivity and sensitivity. The Car/PDMS fiber was shown to be the most efficient at extracting the 10 selected volatile organic acids. The parameters were optimized: $80^{\circ}C$ adsorption temperature, 30 min of adsorption time, $240^{\circ}C$ desorption temperature, 1 min of adsorption time.

문제 정의

This study shows that a combination of SPME with a gas chromatograph with mass spectrometer can be used to accurately determine 10 selected volatile organic acids in tobacco. This method allowed us to make important improvements in selectivity and sensitivity.

제안 방법

The limit of detection (LOD) for the procedure was calculated on a signal-to -noise basis of 3:1. Recovery tests were carried out at three spiking levels and 3 replicates. An analyte solution was spiked to the tobacco to achieve concentrations of 0.
spectrometer (USA). This instrument was equipped with a CTC CombiPAL autosampler (CTC Analytics, USA), which automated the SPME analysis. An analytical capillary column was used VF-5ms (30m × 0.

성능/효과

4. Desorption temperature : The analyte can be desorbed effectively under a higher temperature in a shorter time, but the stability and the life-time of the fiber will be affected. Also the analyte may be decomposed if the desorption temperature is too high.
