The extracts were then be analyzed by GCMS. Unfortunately, the GCMS instrument had a technical dysfunction before the final experiments could be performed. Despite that, it is shown that although it required a more complicated method development, SPME has better accuracy when analyzing the CPZ content of the samples than MEPS. However, the study still needs further investigation for strengthening the findings36enMicroextraction by Packed Sorbent (MEPS), Solid-Phase Microextraction (SPME), Chlorpromazine.DEENK Témalista::Kémia::Analitikai kémia
