The effect of hematocrit on solid-phase microextraction [PDF]

open access: yesAnalytica Chimica Acta, 2018
Solid-phase microextraction (SPME) is an approach to sample preparation that has demonstrated its appropriateness for isolating/enriching analytes present in complex biofluids with minimum sample pre-treatment. Several prior in vitro and in vivo studies have used SPME to monitor the concentrations of various drugs and metabolites in blood samples.
