5% Carbowax 20M / Carbopack B 是测定甲醇的“黄金标准”色谱柱之一。 方法核心是：
使用FID检测器。
采用较低的起始柱温（50-80°C）。
可以直接进水溶液样品。
该方法能很好地分离甲醇、乙醇、丙酮、异丙醇等常见挥发性组分。
建议您先从推荐的等温条件开始尝试，观察甲醇的峰形和保留时间，再根据实际样品中的其他组分情况优化温度程序。
“5% Carbowax 20M / Carbopack B” 结合了极性固定液和惰性石墨化炭黑载体的优点。它对极性小分子化合物（C1-C5的醇、醛等）具有极高的分离效率和对称的峰形，能有效避免拖尾现象，非常适合分析像甲醇、乙醇、丙酮、乙醛等常见挥发性有机物。

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".
