| 摘 要： | 微捕集实际上是一种动态顶空技术。微捕集技术通常处理小体积的样品,应用小流量气体吹扫和小尺寸吸附管捕集,与仪器在线联接成一体的直接进样分析方法,不需要柱前冷聚焦和柱前分流的过程。该技术具有较好的应用前景。

| Abstract: | Micro-trapping technique is a kind of dynamic headspace technique actually. It is usually used to treat small volume samples. We analyse samples with small flow of gas purge and small size of adsorption tube trap connected with instrument online. This method doesn't need pre-column focusing and pre-column cold shunt,and it has better prospect. |
