【求助】求高人帮翻译一下

A gas chromatograph with a capillary column coupled to a mass spectrometric detector (electron ionisation,EI) is used for the analysis.

本分析使用了具有偶合质谱检测器（电离子化，EI）毛细管柱的气相色谱（气质联仪）。

见笑

the mass spectrometric detector shall be able to perform selective ion monitoring and have an upper mass range of at least 1000 m/z.

质谱检测器可以进行选择性的离子监测，上限质量范围至少是1000m/z

谢谢！后面的能帮忙翻译下不？

high-range mass is required to unambiguously identify DecaBDE and NonaBDE.

为明晰确定DecaBDE和NonaBDE，需要high-range mass（高分辨质谱？？？）

the use of an autosampler is strongly recommended to ensure repeatability .
为确保重复性，特别建议使用自动进样器。

a column length of approximately 15 m has sufficient separation efficency for PBB and PBDE compounds.
对于PBB和PBDE化合物来讲，大约15米的柱长足够达到分离效率（效果，踏板数？？？）

非常感谢！

There is no doubt that one of the translations of couple is 偶合.

But in structural engineering, the connection of two reinforcing bars can be by means of a coupler. Would it be possible that “coupled to” means connected to? (I have no knowledge about the gas chromatograph and mass spectrometric detector)

感觉上耦合两个字可以去掉，原文想说明的应该是带有质谱检测器的毛细管柱气相色谱仪。
