“407有機擔體填充柱”就是指將407這種多孔聚合物顆粒，緊密、均勻地填充在一根金屬（如不銹鋼）或玻璃材質(zhì)的管狀柱體中。
柱管：通常為不銹鋼管，內(nèi)徑2-4 mm，長度1-3米，盤成螺旋狀。
填充物：407有機擔體顆粒（通常目數(shù)為60-80目或80-100目）。
主要特點與優(yōu)勢
出色的水分析能力：水峰出峰早且峰形好，不會掩蓋其后流出的有機組分，非常適合有機物中微量水分的測定，或者水溶液中有機物的分析。
分離極性化合物：對醇、 glycols（乙二醇、丙二醇）、醛、酮、短鏈有機酸等有很好的分離效果。
峰形對稱：由于擔體惰性好，能減少極性分子的拖尾現(xiàn)象。
壽命較長：相比一些涂漬液膜的毛細管柱，填充柱更“皮實”，不易被污染樣品損壞。
常見于：
化工行業(yè)：
醇類混合物分析：如甲醇、乙醇、異丙醇、正丙醇、丁醇等。
有機溶劑中的水分含量測定。合成反應(yīng)監(jiān)控：如醇醚、酯化反應(yīng)等。
環(huán)境監(jiān)測：水中揮發(fā)性有機物（VOCs）的分析，但在此領(lǐng)域正逐漸被更高效的毛細管柱取代。
食品和飲料：酒類、飲料中醇類、醛類風味物質(zhì)的分析。
** pharmaceuticals**：藥物合成過程中溶劑殘留（如甲醇、乙醇、丙酮）的檢測。

The "407 Organic Carrier Filled Column" refers to tightly and uniformly filling porous polymer particles of 407 into a tubular column made of metal (such as stainless steel) or glass material.
Column tube: usually made of stainless steel, with an inner diameter of 2-4 mm and a length of 1-3 meters, coiled in a spiral shape.
Filler: 407 organic support particles (usually 60-80 mesh or 80-100 mesh).
Main features and advantages
Excellent water analysis ability: The water peak appears early and has a good peak shape, which does not mask the organic components that flow out afterwards. It is very suitable for the determination of trace water in organic matter or the analysis of organic matter in aqueous solutions.
Separation of polar compounds: It has good separation effects on alcohols, glycols (ethylene glycol, propylene glycol), aldehydes, ketones, short chain organic acids, etc.
Peak symmetry: Due to the good inertness of the carrier, it can reduce the tailing phenomenon of polar molecules.
Longer lifespan: Compared to some capillary columns coated with liquid film, packed columns are more "robust" and less susceptible to damage from contaminated samples.
Commonly seen in:
Chemical industry:
Analysis of alcohol mixtures: such as methanol, ethanol, isopropanol, n-propanol, butanol, etc.
Determination of moisture content in organic solvents. Synthesis reaction monitoring: such as alcohol ether, esterification reaction, etc.
Environmental monitoring: analysis of volatile organic compounds (VOCs) in water, but this field is gradually being replaced by more efficient capillary columns.
Food and beverages: analysis of alcohol and aldehyde flavor compounds in alcoholic beverages.
**Pharmaceuticals * *: Detection of solvent residues (such as methanol, ethanol, acetone) during drug synthesis.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "407 Organic Carrier Chromatography Column Application Agilent 6890":
Detection of residual ethylene oxide (EO) in pharmaceutical packaging materials (commonly used headspace gas chromatography method)
