Stationary source emissions. Determination of mass concentration of fluorinated compounds expressed as HF. Standard reference method
This document specifies a manual method for the determination of the concentration of fluorinated compounds expressed in HF.
First case: the measurand is the concentration of gaseous and bound to particulates fluorides;
Second case: the measurand is the concentration of gaseous fluorides.
Three analytical techniques are proposed: ionometry, spectrophotometry and ion-exchange chromatography.
This document specifies the performance characteristics to be determined and the performance criteria to be fulfilled when it is used as the Standard Reference Method (SRM) for periodic monitoring and for calibration or control of Automated Measuring Systems (AMS) permanently installed on a stack, for regulatory or other purposes.
This document applies to fluoride concentrations which may vary between 0,1 mg HF/m3 and 10 mg HF/m3, at standard conditions of pressure and temperature (see NOTE).
The limit of quantification of the method is estimated at 0,1 mg/m3 for a sampled volume of 0,1 m3.
Interference may occur for some matrices. Known elements that may lead to interference are mentioned in Annex C.
NOTE The Emission Limit Values (ELV) for HF are expressed in mg/m3, for dry gases at the standard conditions (Tstd = 273 K and Pstd = 101,3 kPa).
