摘要
文章介绍了利用安捷伦7890气相色谱—双等离子体硫化学发光检测器分析仪,分析气体中的痕量羰基硫、硫化氢、甲硫醇、二甲二硫、二乙二硫的方法。研究了最佳测试条件。选用外标法为定量依据,采用仪器在线稀释功能,分析操作过程简单方便。测定结果的准确度高于95%,方法的检出限达到5 ppb,分析结果准确可靠。适用于石化工业气体中痕量及微量硫组分及总硫分析。
The paper describes the use of Agilent 7890 GC dual plasma sulfur chemiluminescence detector analyzer, gas analysis method of trace carbonyl sulfur, hydrogen sulfide, mercaptan sulfur, two, two a two B two sulfur. Study on the optimum conditions. The external standard method for quantitative basis, using on-line dilution function analysis instrument, simple and convenient operation process. The measurement accuracy is higher than 95 %, the detection limit of the 5 ppb method, the analytical results are accurate. Suitable for petrochemical industrial gases and trace trace sulfur composition and total sulfur analysis.
