Abstract: | Gas chromatography with Fourier transform infra-red spectroscopic detection (GC-FTIR) is used for the analysis of waste water samples. Compared to GC-MS, this technique offers a more complete identification of organic compounds. Lower concentrations of organic volatiles however require preconcentration techniques such as a Purge and Trap (P&T) preconcentrator. Using this combination, concentrations of organic volatiles in the ppb range can be detected and positively identified. |
