The extinguishing of the oxy-hydrogen flame between combustion operations in the treatment of an organic substance in the flame to determine its sulphur and halogen content is prevented by providing a multichannel cock H1 between the absorption bulb A2 - A9 which is connected to the oxy-hydrogen burner B1 and an interchangeable flask A11 into which the reaction gases contained in an absorption solution introduced at A4 flow for final analysis. The substance under analysis is placed in container B2 and heated externally by a Bunsen burner, the vapours therefrom passing to the combustion chamber A2 which is under the action of the oxy-hydrogen flame, the oxygen and hydrogen 'being fed through meters S2 and S3. The reaction vapours are condensed at A3 and are then mixed with the absorption solution before passing through a plurality of perforated bases A5 and a fine pored frit A7 to the flask, the entire apparatus including the flask being under vacuum through connection A8. |
