4. Optimizing solid-phase microextraction
When developing a preconcentration method using solid-phase microextraction, several parameters need to be optimized:
extraction mode ;
the nature of the polymer ;
the time required to achieve equilibrium in compound distribution between matrix and polymer;
the desorption time of polymer compounds.
The choice is between direct or headspace extraction. The efficiency of each technique depends on the physico-chemical characteristics of the compounds to be extracted and the nature of the matrix. In general, for liquid matrices, direct extraction is more sensitive, but the...
