Chromosorb 104 因其強(qiáng)極性和對(duì)含氮、氧官能團(tuán)化合物的強(qiáng)保留能力而聞名，特別適用于以下分析：
水樣分析： 這是它最著名的應(yīng)用之一。它可以直接進(jìn)水樣分析水中的揮發(fā)性極性有機(jī)物，而水峰出峰很早，對(duì)稱(chēng)性好，不拖尾，對(duì)后續(xù)組分的干擾很小。這是很多其他固定相難以做到的。
醇、醛、酮類(lèi)化合物： 對(duì)低級(jí)醇（甲醇、乙醇、異丙醇等）、甲醛、乙醛、丙酮等有很好的分離效果。
腈類(lèi)化合物： 如丙烯腈、乙腈等。
氨和胺類(lèi)： 對(duì)氨、甲胺、二甲胺等有較強(qiáng)的保留和良好的分離。
氣體分析： 可用于分析永久性氣體（如CO?、N?O）以及硫化氫、二氧化硫等酸性氣體，但在分析酸性氣體時(shí)可能存在不可逆吸附的風(fēng)險(xiǎn)。
環(huán)境監(jiān)測(cè)： 用于分析大氣和水體中的痕量極性污染物。
3. 優(yōu)點(diǎn)
耐水性極佳： 可以直接分析水溶液樣品，這是其相對(duì)于許多硅油類(lèi)固定相的巨大優(yōu)勢(shì)。
惰性較好： 對(duì)活性化合物（如醇、胺）的吸附性較低，能獲得對(duì)稱(chēng)的色譜峰。
無(wú)流失： 作為聚合物固定相，它沒(méi)有像液相固定相那樣的“流失”問(wèn)題，基線(xiàn)相對(duì)穩(wěn)定，適用于對(duì)靈敏度要求高的檢測(cè)器（如MS）。
重現(xiàn)性好： 作為合成聚合物，不同批次間的性能相對(duì)穩(wěn)定。

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 ?, N ? 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.
3. Advantages
Excellent water resistance: It can directly analyze aqueous solution samples, which is its huge advantage over many silicone oil stationary phases.
Good inertness: Low adsorption of active compounds (such as alcohols and amines), able to obtain symmetrical chromatographic peaks.
No loss: As a polymer stationary phase, it does not have the "loss" problem like liquid stationary phases, and the baseline is relatively stable, making it suitable for detectors with high sensitivity requirements (such as MS).
Good reproducibility: As a synthetic polymer, the performance between different batches is relatively stable.
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.
