Rtx-5 Amine与Rtx-5(5%二苯基/95%二甲基聚硅氧烷)具有同样的极性，但是Rtx-5 Amine柱经过不同于常规的特殊处理，有效地消除了管壁上存在的硅醇基团(SiOH)的影响。因此Rtx-5 Amine柱最适宜于单、双、叁胺类化合物,乙醇胺和其它烷基醇类化合物的分析。
Rtx-5 Amine柱经独特的去活技术处理，减少了碱性化合物在柱上的吸附现象，改善了它的响应值。原先要通过衍生化或用液相色谱分析的活性碱性化合物，也就可在该柱上得到分析。该柱在不经起动处理的情况下，可分析PPm级的胺类化合物。

Rtx-5 Amine除适宜于分析烷基胺类、二胺类、三胺类、乙醇胺类和含氮杂环（nitrogen-Containing heterocycles）化合物的分析，同时突破性的处理技术也允许该柱分析中性化合物，易形成氢键的含氧吸附化合物的分析，甚至可分析酚类等中等的酸性化合物。可直接注入以水为基质的样品。
每一支Rtx-5 Amine都经过配有碱性，中性和含氧化合物的混合试验样品的特别试验。并附有程序升温色谱图和实际试样色谱图，以阐明每个柱的低流失和碱性化合物的重复分析的情况。Rtx-5 Amine柱均为交联键合柱，可用一般的有机溶剂淋洗而恢复性能。
该柱类似于PTA-5柱。

Rtx®-5 Amine (Fused Silica)
The Rtx®-5 Amine column provides consistent and reproducible results for analyzing basic compounds--Guaranteed!

Application-specific columns for amines and other basic compounds, including alkylamines, diamines, triamines, ethanolamines, and nitrogen-containing heterocyclics.

Stable to 315°C.


Active basic compounds that otherwise require derivatization, or an alternative analytical technique, can be analyzed on an Rtx®-5 Amine column. The tubing surface is chemically altered to reduce tailing of basic compounds, eliminating the need for column priming. An Rtx®-5 Amine column is ideal for analyzing a wide variety of basic compounds, but breakthrough technology also allows the analysis of neutral compounds, adsorptive compounds with oxygen groups susceptible to hydrogen bonding, or even weakly acidic compounds such as phenols. Every Rtx®-5 Amine column is tested to ensure that it exceeds the requirements for analyzing ppm levels of amines, without priming, and to ensure low bleed at maximum operating temperature.
