A simple approach to on-line oxidative pyrolysis-capillary gas chromatography—Mass spectrometry

Novel stir bar sorptive extraction methods for environmental and biomedical analysis

“…Therefore, SBSE with in situ derivatization, wherein derivatization and SBSE are performed at the same time, was developed [48,[56][57][58][59][60][61][62][63][64][65][66][67][68][69]. The derivatization of a phenolic hydroxyl group with acetic acid anhydride (AA) [56][57][58][59][60][61][62][63][64][65][66][67][68], a carboxyl group with ethyl chloroformate (ECF) [56][57][58] and carbonyl compounds with O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine (PFBHA) [48] has been reported. In addition, the determination of organotin in water sample by SBSE with in situ derivatization using sodium tetraethylborate (NaBET 4 ) has been reported [69].…”

Stir bar sorptive extraction with in situ derivatization and thermal desorption-gas chromatography–mass spectrometry for measurement of phenolic xenoestrogens in human urine samples

“…We have reported the determination of OP and NP in tap and river water samples [34] and biological samples [35] by SBSE without derivatization. On the other hand, SBSE with in situ derivatization has been successfully used in the determination of phenolic compounds in various samples [36][37][38][39]. In addition, we have performed the determination of BPA in water and body fluid samples [40], chlorophenols in water and body fluid samples [41], estrogens in water samples [42], and PXs in river water samples [43] by SBSE with in situ derivatization.…”

Determination of bisphenol A in river water and body fluid samples by stir bar sorptive extraction with in situ derivatization and thermal desorption-gas chromatography–mass spectrometry

“…In addition, SBSE has been applied successfully in biological samples [29][30][31][32][33]. An SBSE method that employs in situ derivatization was used in the analysis of phenolic compounds [31][32][33].…”

“…The technique is known as stir bar sorptive extraction (SBSE) and its main advantage is its wide application range that can include volatile aromatics, halogenated solvents, polyaromatic hydrocarbons, polychlorinated biphenyls (PCBs), pesticides, preservatives, odor compounds, and organotin compounds [24][25][26][27][28][29][30][31][32][33]. In addition, SBSE has been applied successfully in biological samples [29][30][31][32][33]. An SBSE method that employs in situ derivatization was used in the analysis of phenolic compounds [31][32][33].…”
