Sulfur recovery unit in tail gas H2S, SO2 content is low, the original Klaus recovery unit process gas chromatographic analysis methods can not adapt to requirement.

 xiang ying analysis technology co., LTD., through the experiment many times, to establish a new approach for the analysis of exhaust gas H2S, SO2 content - use GC7990FPD gas chromatograph analysis method. This method is mainly in the chromatographic column and chromatographic conditions have larger changes, compared with the original chromatography has the characteristics of fast and accurate, and suitable for control analysis of the production process.

            硫磺回收裝置尾氣中H2S、SO2含量很低，原有的克勞斯回收裝置過程氣色譜分析方法不能適應要求。

           滕州市翔鷹分析技術有限公司通過多次實驗，建立了分析尾氣H2S、SO2含量的新方法——用GC7990FPD氣相色譜儀分析方法。該方法主要在色譜柱和色譜條件方面較原色譜法有較大的改變，具有快捷準確的特點，適合于生產過程的控制分析。
