浩瀚Chromosorb 104填充柱应用在安捷伦7890B上2m*3mm

Chromosorb 104 是气相色谱发展历史上的一款经典强极性填充柱固定相，以其卓越的耐水性和对极性化合物的优异分离能力而著称。虽然它现已停产，但了解其特性对于理解许多标准分析方法（如水中挥发性有机物的分析）的历史和原理仍然非常重要。

Chromosorb 104 因其强极性和对含氮、氧官能团化合物的强保留能力而闻名，特别适用于以下分析：
水样分析： 这是它*应用之一。它可以直接进水样分析水中的挥发性极性有机物，而水峰出峰很早，对称性好，不拖尾，对后续组分的干扰很小。这是很多其他固定相难以做到的。
醇、醛、酮类化合物： 对低级醇（甲醇、乙醇、异丙醇等）、甲醛、乙醛、丙酮等有很好的分离效果。
腈类化合物： 如丙烯腈、乙腈等。
氨和胺类： 对氨、甲胺、二甲胺等有较强的保留和良好的分离。
气体分析： 可用于分析永久性气体（如CO₂、N₂O）以及硫化氢、二氧化硫等酸性气体，但在分析酸性气体时可能存在不可逆吸附的风险。
环境监测： 用于分析大气和水体中的痕量极性污染物。
3. 优点
耐水性极佳： 可以直接分析水溶液样品，这是其相对于许多硅油类固定相的巨大优势。
惰性较好： 对活性化合物（如醇、胺）的吸附性较低，能获得对称的色谱峰。
无流失： 作为聚合物固定相，它没有像液相固定相那样的“流失”问题，基线相对稳定，适用于对灵敏度要求高的检测器（如MS）。
重现性好： 作为合成聚合物，不同批次间的性能相对稳定。

Chromosorb 104 is a classic strongly polar packed column stationary phase in the history of gas chromatography, known for its excellent water resistance and outstanding separation ability for polar compounds. Although it has been discontinued, understanding its characteristics is still crucial for comprehending the history and principles of many standard analytical methods, such as the analysis of volatile organic compounds in water.
Chromosorb 104 is renowned for its strong polarity and strong retention ability for nitrogen-containing and oxygen-containing functional compounds, making it particularly suitable for the following analyses:
Water sample analysis: This is one of its most famous applications. It can directly analyze volatile polar organic compounds in water samples, and the water peak appears very early, with good symmetry, no tailing, and minimal interference with subsequent components. This is something that many other fixed phases find difficult to achieve.
Alcohols, aldehydes, ketones: have good separation effects on lower alcohols (methanol, ethanol, isopropanol, etc.), formaldehyde, acetaldehyde, acetone, etc.
Nitrile compounds: such as acrylonitrile, acetonitrile, etc.
Ammonia and amines: have strong retention and good separation for ammonia, methylamine, dimethylamine, etc.
Gas analysis: can be used to analyze permanent gases (such as CO ₂, N ₂ O) as well as acidic gases such as hydrogen sulfide and sulfur dioxide, but there may be a risk of irreversible adsorption when analyzing acidic gases.
Environmental monitoring: used to analyze trace polar pollutants in the atmosphere and water bodies.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "Chromosorb 104 Filled Chromatography Column Application Shimadzu GC2014":
It is a highly polar polymer chromatographic packing material and a classic choice for solving the analysis problems of polar substances (especially water, methane, and alcohols) in gas chromatography.
