Abstract Scope New measurement techniques aiming to improve the understanding of PAH emissions dynamics during production of electrode mass briquettes from anthracite (coke) and pitch was tested. Traditional sampling requires hours of sampling to get enough PAH on the adsorbent material to perform reliable analysis. As the process parameters can be changing from one batch to the next, emissions cannot be expected to be constant over time. Better time resolution is essential to increase the understanding of emission variations. Thermal desorption tubes allows for sampling times as short as 10 minutes, and the use of SINTSENSE, a standalone photoionization detector (PID) implementation for emission monitoring. It gives online data second by second, however the SINTSENSE will report a total hydrocarbon estimate, with no differentiation between individual components. Comparing results from these 3 methodologies gives insight in the emission dynamics and variations in composition, in addition to benchmarking of the individual measurement techniques.
