Abstract:
1. Analytical apparatus for performing a method comprising the steps of: mixing a chloride containing sample with a low-volatile acid, wherein hydrochloric acid gas arises, which is present in dissolved form in the sample-acid mixture; purging the hydrochloric acid gas by a carrier gas from the sample-acid mixture; removing the hydrochloric acid gas from the carrier gas following said purging; feeding the carrier gas back to the sample-acid mixture, wherein the sample-acid mixture has a temperature of approximately 3° C. to 30° C.; and following said purging from the sample-acid mixture, the hydrochloric acid gas is removed from the carrier gas by absorption with water; the apparatus comprising: a purging apparatus accommodating said sample-acid mixture; a gas inlet for a carrier gas connected with said purging apparatus; a separation chamber; and an absorption chamber, wherein: said purging apparatus is closed to the atmosphere and leads to said separation chamber adjoined by said absorption chamber for the separating of a hydrogen chloride gas from the carrier gas; and an outlet of said absorption chamber is connected with a gas discharge for the carrier gas; said absorption chamber has a zone wetted with water; and the water reacts with the hydrochloric acid gas to form an absorbate.
