Stationary source emissions - Determination of the mass concentration of total gaseous organic carbon in flue gases from solvent using processes - Continuous flame ionisation detector method

This European Standard specifies a set of minimum performance requirements for an instrument using flame ionisation detection, together with procedures for its calibration and operation, for the measurement of the mass concentration of total gaseous organic carbon (TOC) in flue gases.
This European Standard is suitable for the measurement of gaseous or vapour phase TOC emissions from Solvent Using Processes.
NOTE 1   See Council Directive 1999/13/EEC.
The results obtained using this standard are expressed in milligrams per cubic metre as total carbon (mg/m3). This standard is suitable for the measurement of concentrations from 20 mg/m3 to 500 mg/m3 but can be used at lower concentrations.
NOTE 2   By its nature a flame ionisation detector (FID) can also be used to measure higher concentrations.
The method specified in this European Standard can be used as a reference method or, with suitable minimum operational requirements, for continuous monitoring.  It can also be used for the calibration of automated measuring systems.  An indication of the uncertainty of the measurement is shown in annex A.

4 Principle
4.1 General
There are two elements to the extractive TOC analytical system described in this standard.
They are the FID and the associated sampling device.
4.2 Flame ionisation detector
The measurement principle is the determination of an ionisation current resulting from the
combustion of organic compounds in a hydrogen flame. This current 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 main advantage of the FID is that it responds strongly to organic carbon containing
components and less to inorganic flue gas components (such as CO, CO , NO, H O).
2 2
FIDs require a fuel gas and combustion air.

Figure 1: Diagram of the FID measuring principle (example)
A number of different instrument configurations exist. Figure 1 indicates the principle
whereby in the detector a sample gas is fed into a hydrogen 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 methods 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 span gas for which the response
factor, defined in this standard, has been set at 1.
4.3 Sampling and sampling device
The following principles shall be followed during sampling:
- sampling is the process of extracting from a large quantity of flue gas a small portion
which is truly representative of the composition of the main gas stream;
- the sampling device is equipped with a filter to remove fine particles which could clog the
burner. Condensation downstream of the filter shall be avoided, two methods can be used:
- a line heated up to the inlet of the analyser,
