Always based on the use of IR spectrophotometry, a novel attenuated total reflection-Fourier-transform infrared (ATR-FTIR) sensor [42] was proposed for the on-line monitoring of a dechlorination process. Organohalogenated compounds such as trichloroethylene (TCE), tetrachloroethylene (PCE) and carbon tetrachloride (CT) were detected with a limit of a few milligrams per litre, after extraction on the ATR internal-reflection element coated with a hydro-phobic polymer. As for all IR techniques, partial least squares (PLS) calibration models are needed. As previously, this system is promising for bioprocess control and optimization.

The analysis of organohalogen substances (OHS) in biological samples includes extraction of the OHS and the lipids from the matrix, removal of the lipids, separation of various classes of OHS and finally, detection and quantification. As pointed out above, PCNs have physical and chemical properties similar to the PCBs and the methods used to analyze PCBs and PCNs are therefore rather similar.
