5% Carbowax 20M / Carbopack B 是測(cè)定甲醇的“黃金標(biāo)準(zhǔn)”色譜柱之一。?方法核心是：
使用FID檢測(cè)器。
采用較低的起始柱溫（50-80°C）。
可以直接進(jìn)水溶液樣品。
該方法能很好地分離甲醇、乙醇、丙酮、異丙醇等常見(jiàn)揮發(fā)性組分。
建議您先從推薦的等溫條件開(kāi)始嘗試，觀察甲醇的峰形和保留時(shí)間，再根據(jù)實(shí)際樣品中的其他組分情況優(yōu)化溫度程序。
?
“5% Carbowax 20M / Carbopack B” 結(jié)合了極性固定液和惰性石墨化炭黑載體的優(yōu)點(diǎn)。它對(duì)極性小分子化合物（C1-C5的醇、醛等）具有極高的分離效率和對(duì)稱的峰形，能有效避免拖尾現(xiàn)象，非常適合分析像甲醇、乙醇、丙酮、乙醛等常見(jiàn)揮發(fā)性有機(jī)物。

5% Carbowax 20M/Carbopack B is one of the "gold standard" chromatographic columns for determining methanol. The core of the method is:
Use FID detector.
Use a lower starting column temperature (50-80 ° C).
You can directly sample the water solution.
This method can effectively separate common volatile components such as methanol, ethanol, acetone, isopropanol, etc.
We suggest that you start with the recommended isothermal conditions, observe the peak shape and retention time of methanol, and then optimize the temperature program based on the actual composition of other components in the sample.
5% Carbowax 20M/Carbopack B combines the advantages of polar fixative and inert graphitized carbon black carrier. It has extremely high separation efficiency and symmetrical peak shape for polar small molecule compounds (such as C1 to C5 alcohols, aldehydes, etc.), which can effectively avoid tailing phenomenon. It is very suitable for analyzing common volatile organic compounds such as methanol, ethanol, acetone, acetaldehyde, etc.
If you need to purchase graphitized carbon black packed columns that comply with HJ/T 33-1999 standards (such as 5% Carbowax 20M/Carbopack B), you can contact Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. They provide different specifications (such as 2m * 3mm) of products for the development of "Determination of Methanol in Fixed Pollution Source Exhaust Gas PE Chromatography Columns".
