发明名称 Method and apparatus for removing chloride from samples containing volatile organic carbon
摘要 A method for removing chloride from samples containing volatile organic carbon, wherein a chloride containing sample is mixed with a difficultly volatile acid, wherein hydrochloric acid gas arises, which is present in dissolved form in a sample-acid mixture and then the hydrochloric acid gas is purged by a carrier gas from the sample-acid mixture, wherein the hydrochloric acid gas is removed from the carrier gas following the purging and the carrier gas is fed back to the sample-acid mixture. In order during the hydrochloric acid purging largely to suppress the driving out of easily volatile organic compounds, the sample-acid mixture has a temperature of approximately 3° C. to 30° C., wherein, following the purging from the sample-acid mixture, the hydrochloric acid gas is removed from the carrier gas by absorption with water.
