Quantitative determination of carbon monoxide in blood by gaschromatography.
The gaschromatographic determination of CO in blood has been simplified by using carbon molecular sieve columns for separation of gases. Regeneration of the columns is necessary only after 1000 and more analyses. Moreover, a more simple procedure for evaluating the CO concentration was developed. This procedure is suitable for routine determination in the sensitivity range of 0.2—100 % COHb in ...
متن کاملDetermination of volatile organic compounds by headspace trap.
A new analytical method for the determination of halogenated and aromatic volatile organic compounds in groundwater, mineral water, and drinking water at concentrations ranging between 1-10000 ng/L is developed. A new type of headspace sampler that combines static headspace sampling with a trap is used, yielding very low detection limits and good repeatability without carryover effects. An unex...
متن کاملDetermination of benzene in urine by static headspace gas chromatography.
This paper describes the application of static headspace gas chromatography in determining benzene in urine. The method was analytically validated for sensitivity (DL = 42 ng/l), repeatability (RSD = 3% and 4%), and accuracy (71%), and was applied in measuring urine benzene in nonsmokers (N = 14) and smokers (N = 18). All urine samples had measurable benzene concentrations. The method proved se...
متن کاملDetermination of microstickies in recycled whitewater by headspace gas chromatography.
This study proposed a novel headspace gas chromatographic (HS-GC) method for determination of adhesive contaminants (microstickies) in recycled whitewater, a fiber containing process stream, in the paper mill. It is based on the adsorption behavior of toluene (as a tracer) on the hydrophobic surface of microstickies, which affects the apparent vapor-liquid equilibration partitioning of toluene....
متن کاملDetermination of Cadmium by Electrothermal Atomic Absorption Spectrometry after its Separation and Preconcentration by Syringe to Syringe Dispersive Liquid Phase Microextraction-Solidified Floating Organic Drop
The application of syringe to syringe dispersive liquid phase microextraction-solidified floating organic drop was extended for the separation and preconcentration of trace amounts of cadmium ions from water and cereal samples. The extracted cadmium was quantified by electrothermal atomic absorption spectrometry. Factors affecting the complex formation as well as microextraction efficiency such...
