According to this standard, an integrated sample is representatively extracted by a heated probe from the duct conveying the gases to be analyzed. Particles and dusts are separated from the sampled gases by a controlled temperature high efficiency filter. The hydrogen chloride is absorbed in an absorption reagent (chloride free water) according to prEN 1911-2. The resulting absorption solution is subsequently analyzed according to prEN 1911-3. All compounds which are volatile at the filtration temperature and produce chloride ions upon dissolution during sampling are measured by this method, which gives therefore the volatile inorganic chlorides content of gases expressed as HCl. In most cases, this correspond to the hydrogen content of gases expressed as HCI.In most cases, this correspondents to the hydrogen content; if necessary an indicative distinction between hydrogen chloride and volatile chlorides may be achieved, using additional checks. The method described applies to ducted gaseous streams emitted by waste incinerators and more generally to waste gases in which HCI concentration may vary between 1 mg.m-3 and 5000 mg.m-3 under normal pressure and temperature conditions. Interferences may occur with some substances, and special care is needed for sampling of water vapor saturated gases (i.e. gases downstream a wet scrubber without subsequent reheating).
