DIN EN 12619:2013-04 EN 12619:2013 (E) 4 1 Scope This European Standard specifies a flame ionisation detector (FID) method. It is intended for use as a standard reference method for the measurement of the mass concentration

26、of gaseous and vaporous organic substances (expressed as TVOC) in stationary source emissions (e.g. emissions from waste incinerators and solvent using processes, emission measurements according to 2010/75/EU) in the concentration range up to 1 000 mg/m. This European Standard specifies the requirem

27、ents for an instrument using flame ionisation detection, together with procedures for its operation. The results obtained using this standard are expressed in milligrams per cubic metre (mg/m) as total carbon (TVOC). This European Standard is not applicable for permanently installed automated measur

28、ing systems (AMS). Alternative methods to this method may be used provided that the user can demonstrate equivalence, based on the principles of CEN/TS 14793. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for it

The ionisation current measu

41、red by the FID depends on the number of C-atoms of organic compounds burning in the fuel gas flame, the form of bonding (straight chain or branched chain) and of bonding partners. The response factor is a function of the specific design of the detector and the adjusted operating conditions. The adva

42、ntage of the FID is that it responds to organic carbon compounds and has negligible response to inorganic flue gas compounds (such as CO, CO2, NO, H2O). A number of different instrument configurations exist. Figure 1 is an example of the principle whereby in the detector a sample gas is fed into a h

43、ydrogen flame across which a DC electrical potential is placed. The introduction of the sampled gas causes a specific ionisation current to flow, which is measured using suitable equipment. Defined test gases are required to determine the response factors. These can be produced by a number of method

44、s including: static methods (with gas collectors or direct injection) or dynamic methods (e.g. vapour pressure method or certified test gases from compressed gas bottles). The span of the instrument shall be adjusted with propane (C3H8) for which the response factor, defined in this standard, has be

45、en set at 1,00. The final value will be expressed as TVOC in milligrams per cubic metre. Refer to Annex B for more information on the use and effects of an FID instrument.

A partial flow of the flue gas is directly fed into the F

The sampling device including the filter needed to remove fine particles, which could clog the burner, is heated to avoid sample condensation.
