Optimization of Headspace Sampling Using Solid Phase Microextraction For Volatile Organic Acids in Different Tobacco Types
Optimization of Headspace Sampling Using Solid Phase Microextraction For Volatile Organic Acids in Different Tobacco TypesSolid-phase microextraction(SPME);volatile organic acids;Selectivity;tobacco;adsorption efficiency;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.
