| Abstract | A miniaturized sample preparation method is presented that is based on microextraction by packed sorbent (MEPS) to determine metabolites of monoterpenes in small volumes of human urine. A protocol including syringe modifications has been developed to exploit the concept of MEPS for application in gas chromatography—mass spectrometry with splitless injection. Only 210 μL of enzymatically hydrolysed urine is needed to carry out a complete extraction protocol. Elution volumes between 1 and 10 μL can be transferred completely or partly to the GC-MS system. All steps of filling and injection of the MEPS syringes are performed automatically. The utility of this approach was demonstrated in terms of determinations of the monoterpene metabolites cis-verbenol, trans-verbenol, α-terpineol, myrtenol and perillyl alcohol in a urine sample of a volunteer who lived in a dwelling with high indoor air exposure of monoterpenes. |
