[交流] 有谁可帮助翻译以下段落?

以下段落牵涉到仪器构造问题,有对气相了解深刻的请帮忙翻译一下,谢谢啦!
Injections of vapour phase may be effected by static or dynamic head-space injection systems.
Dynamic head-space(purge and trap) injection systems include a sparging device by which volatile substances in solution are swept into an absorbent column maintained at a low temperature. Retained substances are then desorbed iinto the mobile phase by rapid heating of the absorbent column.
Static head-space injection systems include a thermostatically controlled sample heating chamber in which closed vials containing solid or liquid samples are placed for a fixed period of time to allow the volatile components of the sample to reach equilibrium between the non-gaseous phase and the vapour phase. After equilibrium has been established, a predetermined amount of the head-space of the vial is flushed into the gas chromatograph.
多谢了!

气相进样受到静态或动态顶空进样系统的。动态顶空进样系统包括一个喷射装置,而溶液中的挥发性物质则通过这个装置被带入低温条件下的吸附柱中。经过对吸附柱加热,被保留的物质迅速在流动相中溶解。静态进样系统则包括一个温控的样品加热室,在这个加热室中,对装有固体或液体样品的密闭小瓶进行加热一定时间后,使得其中的挥发性组分达到气相和非气相的平衡状态。然后,瓶中一定量的顶空气体样品即进入气相色谱进行分析。
