A method based on liquid-liquid-liquid microextraction combined with corona discharge ion mobility spectrometry was developed for the analysis of amantadine in human urine and plasma samples. Amantadine was extracted from alkaline aqueous sample as donor phase through a thin phase of organic solvent (n-dodecane) filling the pores of the hollow fiber wall(More)
A single-drop microextraction (SDME) method followed by in-syringe derivatization and GC-MS determination has been developed for analysis of five parabens, including methyl, ethyl, isopropyl, n-propyl and n-butyl paraben in water samples and cosmetic products. N,O-Bis(trimethylsilyl)acetamide (BSA) was used as derivatization reagent. Derivatization reaction(More)
Analysis of testosterone was accomplished using corona discharge ion mobility spectrometry. Molecular imprinted polymer was used for the extraction and pre-concentration of testosterone. Analytical parameters including precision, dynamic range and detection limit were obtained. The linear dynamic range was from 10 to 250 ng/mL and the limit of detection was(More)
