SERa: Area-specific emission rate 
1)The emission rate is calculated using the detected mass based on the response of the standard, the analyzed sample surface area or number of samples and the sampling duration.
2)Refractories are compounds containing elements other than C, H and O (for example S, P, N,…).
3)Siloxanes and other Si-containing organic substances. Siloxanes also count as refractories.
