| Abstract: | "Although the compound profiles in extracts are linked to the solid-phase microextraction (SPME) position (headspace or liquid), a theoretical interpretation of this scenario has not yet been provided. In this study, the dynamic linked position unity (DLPU)-SPME is proposed as a method that allows balanced extraction of volatile and semi-volatile compounds. Furthermore, the pH, temperature, and salt were confirmed as the key factors affecting the extraction efficiency of DLPU-SPME. Theoretical calculations indicated that K(fs)(0)K(fs) is a key factor directly indicating the SPME extraction position (K(fs)(0)K(fs) > 1, headspace; K(fs)(0)K(fs) = 1, any position; K(fs)(0)K(fs) < 1, in liquid), while the target analytes determined that V(h)K(hs)+V(s)V(e)K(fh)K(hs) regulates the effect of the extraction position on the extracted amount. The proposed DLPU-SPME method containing both extraction positions (i.e., headspace and liquid) can simultaneously extract volatile and semi-volatile compounds, thus avoiding extraction bias" |
