Estimation of BTEX in groundwater by using gas chromatography-mass spectrometry.

Advanced analytical modern technology such as coupling a gas chromatography to a mass spectrometric technique provides sufficient information to the environmental and analytical chemists to identify the presence of a variety of components of the specific volatile organic product, determine the degree of the product weathering and in some instances estimate the age of the product as well in the testing sample. In this study, we estimated BTEX in groundwater sample by using gas chromatography-mass spectrometry (GC-MS) after standardization of this technique for advancement towards purification check of water samples in the petro-polluted regions of the soil.
