主题：【求助】on-column interface

这个词组是从哪里看的？前后的语境是什么样的？说的完整一点。

请问on-column interface 是什么？是不是柱上进样？

我认为是柱上进样的意思。因为，它的直译为柱上面，没动词，需要顺着语境翻。按英文的习惯，动词会在前面加以叙述，本段在前，应是定语前置安排。
个人观点。

on-column interface 可能是柱上接口，例如用于耦合HPLC和GC（或GCMS）之间的连接（或在线HPLC和GC之间的连接）或切换（从HPLC的流分到GC进行分析）。

、

The interfacing utilises techniques developed for large-volume injection,such as on-column,loop-type and vaporiser inerfaces.The benefits and disadvantages of each interface and the solvent evaporation techniques used with them are listed in Table 1.The main parameters to be considered is the applicablity range of the system,i.e. whether volatile analytes or dirty samples can be analysed.Also the simplicity of optimisation is important.If samples are not very dirty,on-column inerface with partially concurrent evaporation is a good choice.For dirty samples,PTV is more suitable.

应该是说得柱上进样。

Abstract
A modified on-column interface is reported for the coupling of high-performance liquid chromatography with gas chromatography, incorporated an adapted, commercially available multidimensional gas chromatography switching system. Novel features include cryogenic analyte focusing, total solvent exclusion from the analytical column and independent carrier gas supplies to the analytical gc column and uncoated pre-column. The instrumentation was used for the determination of the veterinary anthelmintic drug levamisole in milk with analyte detection by both flame ionisation and nitrogen-phosphorus detectors. Detection limits for the assay were 2.2 ωg 1−1 and 0.4 ωg−1 by flame ionisation and nitrogen-phosphorus detectors, respectively. The assay was applied to a survey of fourteen milk samples from different dairy outlets.

应该是柱上进样的选择，前提是样品不是非常赃。

学习了，谢谢大家
