Determination of 9, 10-phenanthrenequinone in airborne particulates by High-Performance Liquid Chromatography with post-column fluorescence derivatization using 2-aminothiophenol.
9, 10-Phenanthrenequinone (PQ) is regarded as a harmful environmental pollutant and its presence has been reported in atmospheric environment. The measurement of PQ in environment should be necessary to evaluate the influence of PQ on human health. We found that PQ reacted with 2-aminothiophenol under acidic condition to form fluorescent derivative which emits green fluorescence at 510nm. Based...
متن کاملHigh Performance Liquid Chromatography Coupled with Pre-column Derivatization for Determination of Oxidized Glutathione Level in Rats Exposed to Paraquat
Glutathione (GSH) is one of the most important antioxidants that plays an essential role in detoxification of reactive oxygen species (ROS) which oxidizes to glutathione disulfide (GSSG). Paraquat (PQ), awidely used herbicide, causes pulmonary injury with the productionof ROS. Excessive ROS accumulation as a consequence of PQ exposure are frequently targeted by GSH thereby oxidative stress lead...

متن کامل[Development of highly sensitive determination of biogenic compounds by high-performance liquid chromatography with pre-column fluorescence derivatization].
A sensitive fluorescent labeling reagent, 4-(5,6-dimethoxy-2-phthalimidinyl)-2-methoxyphenylsulfonyl chloride (DMS-Cl), for the determination of amino compounds in HPLC was developed. DMS-Cl reacted with amino compounds in the basic medium to produce the corresponding fluorescent sulfonamides (excition 318 nm, emission 406 nm in aqueous acetonitrile). When amino acids were analyzed using revers...
متن کاملHigh performance liquid chromatographic determination of acetoacetate by post-column derivatization with p-nitrobenzene diazonium fluoroborate.
We have applied a color-developing reagent, p-nitrobenzene diazonium fluoroborate (diazo reagent) as a post-column derivatization tool for the specific determination of acetoacetate (AcAc) in high performance liquid chromatography (HPLC). A mobile phase consisting of 50 mM KH(2)PO(4), 4 mM tetra-n-butylammonium phosphate (TBAP) as an ion-pair reagent and 2 v/v% methanol, pH 3.5, diazo reagent s...
