Abstract: PURPOSE: Provided is a method for determining hydroxy polychlorinated biphenyls in urine, which is excellent in sensitivity, accuracy, convenience and economical efficiency of time and cost. CONSTITUTION: The method for determining a concentration of hydroxy polychlorinated biphenyls(PCBs) in urine comprises the steps of: adsorption of hydroxy polychlorinated biphenyls in urine onto fibers of solid-phase microextraction(SPME); derivatization of the hydroxy polychlorinated biphenyls adsorbed on the fibers of solid-phase microextraction using trimethylsilyl; and analysis of trimethylsilyl-derived hydroxy polychlorinated biphenyls by gas chromatography or gas chromatography/mass spectrometer. The adsorption step is carried out at a position of headspace at a temperature of 90 deg.C or above for at least 60 minutes and the derivatization step is carried out at the position of headspace at a temperature of 60 deg.C for 5 to 30 minutes.

Abstract: PURPOSE: A simultaneous detection method of Glyphosate, Endothall and Chloramben as herbicides in water samples is provided, thereby easily, accurately and cheaply detecting the herbicides at one time. CONSTITUTION: A simultaneous detection method of Glyphosate, Endothall and Chloramben as herbicides in water samples comprises the steps of: concentrating Glyphosate, Endothall and Chloramben and forming their derivatives with anhydrous trifluoroacetic acid and trifluoroethanol; analyzing their derivatives to prepare a measuring curve for determination of the concentrations of three herbicides; forming derivatives of three herbicides in various environmental samples; and determining the concentrations of three herbicides, wherein the concentration is carried out by using vaporization under vacuum; the formation of derivatives of three herbicides is carried out by heating the mixture of herbicides with trifluoroacetic acid and trifluoroethanol at 60 to 90 deg. C for 30 to 120 minutes; and the concentration of three herbicides is determined by using gas chromatography/mass spectrometer.
