(NPs) with a large surface area and employed it as a novel fiber
coating for extracting and determining volatile compounds from
Ziziphora tenuior in a minimum period of time without using
solvents with head solid-phase microextraction. The simplex
approach was applied to optimize all parameters concurrently.
Major optimized parameters include temperature, extraction time,
and sample weight. In optimal circumstances, the repeatability for
one fiber (n=5) was at the range of 2.8 – 9.2 percent for the sample
compounds, which is given as relative standard division (R.S.D. %).
The approach suggested in this work provides advantages such as
simple usage, short analysis time, cheaper equipment, high relative
recovery, and fiber thermal stability compared to common analysis
approaches. Our findings indicated that γ-Fe2O3@SiO2-PW fibers are
appropriate for the HS-SPME analysis of essential oils.
