Different measurement approaches have been used to characterize PFC emissions coming from aluminum smelting. In the past, those techniques were developed mainly to measure PFC emissions during the so called Anode Effect (AE). More recently, the variable but notable presence of PFC emissions outside AE was confirmed by many authors. In this paper, we analysed the results obtained by using two different PFC measurement approaches: one using an FTIR with in-situ and real time analysis, and one using an extractive procedure with sampling bags and GC-MS analysis integrating all emissions over an extended period of time. Results for the same sampling location are given for both methodologies and their pros and cons are discussed in light of a proper accounting of non-AE PFC’s. These will need to be carefully considered in future measurement campaigns to provide the most accurate information depending on user needs.
