在生产甲醛过程中，降低甲醇的单耗对降低工艺生产成本提高经济效益具有一定的意义，同时甲醛中甲醇含量的大小反映了催化剂活性的好坏及操作过程中的参数控制水平，另一方面甲醇含量的高低也给下游工序带有一定的影响。

甲醛溶液中甲醇分析方法有气相色谱稀释法和近红外法。近红外分析速度快，但具有一定的测量范围需要定期进行数据比对，近红外超出范围需要用气相色谱法稀释后进样分析，气相色谱法稀释进样容易引入测量误差且延长分析时长，并且甲醛对粘膜、上呼吸道、眼睛和皮肤有强烈刺激性，接触其蒸气，引起结膜炎、角膜炎、鼻炎、支气管炎等，因此稀释过程无疑增加了人员接触时长，影响自身健康。

国标GB/T9009-2011中采用的为气相色谱内标法，内标物质为乙醇，乙醇为极易挥发物质，即内标浓度可变性强。

浩瀚色谱（山东）应用技术开发有限公司针对气相色谱法进行方法参数优化，采用《甲醛溶液分析专用填充柱>>式外标法定量实现直接进样测定甲醛中甲醇含量。此柱柱效高，分离好，耐水，寿命长，是浩瀚色谱，的产品,甲醇先出峰,克服了被溶剂水分覆盖带来的定量不利因素.

In the process of producing formaldehyde, reducing the unit consumption of methanol has a certain significance in reducing the production cost and improving the economic benefits. At the same time, the methanol content in formaldehyde reflects the quality of the catalyst activity and the level of parameter control in the operation process. The level of methanol content also has a certain impact on the downstream process.

The analytical methods of methanol in formaldehyde solution include gas chromatography dilution method and near-infrared method. Near-infrared analysis is fast, but it has a certain measurement range and requires regular data comparison. If the near-infrared exceeds the range, it needs to be diluted with gas chromatography and then injected for analysis. Dilution and injection of gas chromatography can easily introduce measurement errors and prolong the analysis time. Formaldehyde is strongly irritating to mucous membranes, upper respiratory tract, eyes and skin. Contact with its vapor can cause conjunctivitis, keratitis, rhinitis, bronchitis, etc. Therefore, the dilution process undoubtedly increases the contact time of personnel and affects their own health.

The national standard GB/T9009-2011 adopts the gas chromatography internal standard method, and the internal standard substance is ethanol, which is a highly volatile substance, that is, the internal standard concentration is highly variable.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. optimizes the method parameters for gas chromatography, and adopts the "Unique Packed Column for Formaldehyde Solution Analysis>>" external standard method to quantitatively realize the direct injection and determination of methanol content in formaldehyde. This column has high column efficiency, good separation, water resistance and long life. It is a unique product in vast chromatography. Methanol is the first peak, which overcomes the quantitative disadvantage caused by being covered by solvent moisture.
