| Abstract: | Summary A HPLC method for the clean up of PCDD and PCDF samples is presented. The method utilizes the possibility of separating compounds according to the number of double bonds by using an amino bonded stationary phase. Aliphatics as well as compounds with higher aromaticity than PCDD/PCDF are removed. In addition, the latter can be collected as one fraction. The fractionation in fast, done in one step and automated. |
