As GC-MS a good technique for separation and identification of compounds form a complex mixture. Paper industry wastewater contains several organic compound including chlorophenols. I want to identify chrlophenolics form paper industry wastewater. Is DB-wax or DB-5 column suitable for the task
DB-5 is suitable for determination of chlorinated compounds and phenols in water.
Depending on the concentrations of chlorophenols in the wastewater, DB-5 column works better, especially after derivatization procedure in GCMS....
Yes. Each column should perform well. You can check my papers on wastewater analusis by several methods by GC.

You'll get better peak shape and isomer separation on the wax column, but it is limited as to the maximum temperature so you'll retain other heavier compounds from your wastewater that may cause you problems in the future. You'll get some tailing (especially for pentachlorophenol) on the DB-5, but you can heat it hotter and get rid of the heavies. If you are looking for other compounds at the same time then then -5 phase is more robust, but if you just want the chlorophenolics I'd probably stick with the wax.
