Definition of reference values in synthetic emission monitoring bench loops

General Paper


Proficiency tests (PTs) are widely used in order to certify capabilities of laboratories, determine and validate uncertainties and validate methods. One of the major difficulties in emission monitoring PTs is due to realisation of a stable and ‘metrological correct’ gas matrix, and, since now, the most common approach is based on emissions gases taken from industrial boilers, from which, therefore, the composition is ‘metrological’ unknown, or on ambient air added with compounds of interest, but, in this case, the chemical behaviour of the matrix may be different from real cases. Synthetic emissions loops give the possibility to fill this gap, but require particular protocols for definition of reference values and their uncertainties. One solution, adopted on the facility realised at RSE research centre in Italy, is shown.
