GAS CHROMATOGRAPHY MASS SPECTROMETRY Trace analysis of chlorophenols in river water samples by stir bar sorptive extraction with in situ derivatization and thermal desorption-gas chromatography-mass spectrometry
Chlorophenols are one on the indicators for monitoring dioxins. It is reported that correlation is between the amount of chlorophenols and dioxin which are generated by garbage incineration. Moreover, if chlorine processing of the phenol in tap water is carried out, chlorophenols are generated and the nasty smell has been a problem. Furthermore, the estrogenic activity of 2,4dichlorophenol as t...
متن کاملMeasurement of benzophenones in human urine samples by stir bar sorptive extraction and thermal desorption-gas chromatography-mass spectrometry.
Determination of benzophenones (BPs) in human urine samples by stir bar sorptive extraction (SBSE) and thermal desorption (TD)-gas chromatography-mass spectrometry (GC-MS) is described. As analytes, BP, its metabolites benzhydrol (BP-OH) and 2-hydroxybenzophenone (2OH-BP), and its derivatives 2-hydroxy-4-methoxybenzophenone (BP-3) and 2-hydroxy-4-methoxy-4'-methylbenzophenone (BP-10) were selec...
متن کاملQuantification of Volatiles in Mammalian Urine by Stir Bar Sorptive Extraction (SBSE) Techniques and Gas Chromatography
Stir Bar Sorptive Extraction (SBSE) has been found as a successful extraction method for profiling volatile and semivolatile putative chemosignaling compounds in hamster and mouse urine. When combined with an automated thermal desorption system (TDSA) for the gas chromatographic analyses, SBSE has proven to be highly reproducible in quantitative comparisons of the urinary profiles. Relative sta...
متن کاملEnvironmentally friendly analysis of emerging contaminants by pressurized hot water extraction-stir bar sorptive extraction-derivatization and gas chromatography-mass spectrometry.
This work describes the development, optimization, and validation of a new method for the simultaneous determination of a wide range of pharmaceuticals (beta-blockers, lipid regulators…) and personal care products (fragrances, UV filters, phthalates…) in both aqueous and solid environmental matrices. Target compounds were extracted from sediments using pressurized hot water extraction followed ...
متن کاملAnalysis of biogenic carbonyl compounds in rainwater by stir bar sorptive extraction technique with chemical derivatization and gas chromatography‐mass spectrometry
Stir bar sorptive extraction is a powerful technique for the extraction and analysis of organic compounds in aqueous matrices. Carbonyl compounds are ubiquitous components in rainwater, however, it is a major challenge to accurately identify and sensitively quantify carbonyls from rainwater due to the complex matrix. A stir bar sorptive extraction technique was developed to efficiently extract ...
