Abstract
Different extraction methods followed by gas chromatography-mass spectrometry (GC/MS) analysis were developed for qualitative and quantitative measurements of the organic compounds in water. The methods were tested for the investigation of THMs and other pollutants in drinking water. The selected ion monitoring (SIM) mode was used for the quantitative work. A capillary column Rtx 5% phenyl methylpolysiloxane, length 30 m x 0.25 mm I.D., 0.25 µm film thickness, was used with the temperature programs from 30°C (1 min), then increased to 40°C at 1°C/min, then 80°C/min to 200°C, kept 2 min, in the selected ion monitoring mode (SIM) or from 30°C (4 min), then increased to 300°C in the SCAN mode.
