Chromatography mass spectrometry and its use in identification in the radiolysis products of polycyclic aromatic hydrocarbons and organic compounds

Full text : Increased attention to the environment is the result of dramatically increased human activity, which in turn is caused by the rapid growth of population of the planet. Extremely powerful tool for control of pollution of different environmental objects - Chromatographic methods to analyze complex mixtures of components. This work is devoted to methods of gas chromatography - mass - spectroscopy and its use in identifying the pollutants of natural environments. Devices that allow obtaining the mass spectra are called mass spectrometers. Sensitivity of gas chromatography-mass spectrometry (typically 10-6-10-9 g) determined by the sensitivity of the mass spectrometer detector. Its essence lies in the fact that the recording of chromatograms is not the full ion current and the most characteristic ions of the substance. With varying degrees of probability in the water identified over 100 individual organic compounds, including PHs. The method of gas chromatography-mass spectrometry identified compounds in natural waters, soils, soil and sediments.
