| 中文摘要 |
| 对不锈钢采样罐(canister)、小钢瓶、气体采样袋和不锈钢采样管(填充TenaxGC)等4种采样装置进行了碳氢天然源采样的可行性研究。发现,不锈钢采样罐密闭性好,内壁吸附少;不锈钢采样管对天然HCs的吸附和解析效率均是或接近100%,故是HCs天然源较为理想的采样装置。小钢瓶和采样袋内壁吸附严重,气袋自身还不断释放一些C6以上碳氢化合物,不适于HCs天然源采样。但采样袋可用于C5以下烃类的采集和贮存。 |
| 英文摘要 |
| The tests were conducted on the Performances of several devices such as polished canister,steel tank, sampling bag and Tenax GC stainless steel tube for sampling HCs emitted from natural sources. It was found that the polished canister is well sealed and has a less wall effect. The Tenax GC tube has excellent performances in absorption and desorption. It is insufficient for steel tank and sampling bag to sample natural HCs over C6 because of their serious wall absorption. However,the sampling bag is useful for sampling and saving HCs bellow C6. |
