用HH-NH3-II色譜柱測定氨中的輕烴組分，是一個在特定工業(yè)場景中（比如監(jiān)控氨氣純度或工藝過程中的雜質(zhì)）可能遇到的分析需求。由于氨（NH?）本身極性很強(qiáng)且具有活性，而輕烴（如甲烷、乙烷、乙烯、丙烷等）多為非極性或弱極性物質(zhì)，兩者性質(zhì)差異大，因此分析時需要妥善處理氨對分析系統(tǒng)的潛在干擾。

HH-NH3-II是一款專為工業(yè)氨水及相關(guān)氣體樣品中氨含量測定而設(shè)計(jì)的專用填充色譜柱1。其固定相為特殊材質(zhì)，能有效分離氨氣并提供良好峰型。該色譜柱規(guī)格通常為2m*3mm，適用于市面上常見品牌的氣相色譜儀，如安捷倫、島津、賽默飛等。
盡管其設(shè)計(jì)初衷是用于測定氨水或氣體中的氨，但通過優(yōu)化色譜條件，理論上也可嘗試用于分離氨基質(zhì)中的輕烴組分，不過需要特別注意氨對色譜系統(tǒng)和檢測器的潛在影響。

The determination of light hydrocarbon components in ammonia using HH-NH3-II chromatography column is an analytical requirement that may be encountered in specific industrial scenarios, such as monitoring ammonia purity or impurities in the process. Due to the strong polarity and activity of ammonia (NH3) itself, while light hydrocarbons (such as methane, ethane, ethylene, propane, etc.) are mostly non-polar or weakly polar substances with significant differences in their properties, it is necessary to properly handle the potential interference of ammonia on the analysis system during analysis.
HH-NH3-II is a specialized packed chromatography column designed for the determination of ammonia content in industrial ammonia water and related gas samples. Its fixed phase is made of special material, which can effectively separate ammonia and provide good peak shape. The specification of this chromatographic column is usually 2m * 3mm, suitable for common brands of gas chromatographs on the market, such as Agilent, Shimadzu, Thermo Fisher, etc.
Although it was originally designed for the determination of ammonia in ammonia water or gas, theoretically it can also be attempted to separate light hydrocarbon components in amino groups by optimizing chromatographic conditions, but special attention should be paid to the potential impact of ammonia on chromatographic systems and detectors.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the Shimadzu GC2014 column for the determination of C1-C2 in ammonia, which effectively separates ammonia (NH3) matrix from various hydrocarbon impurities (such as methane, ethane, ethylene, acetylene, propane, propylene, etc.) and accurately determines the amount.
