通常,要想准确测定化工产品中水分含量是比较困难的,因无论是取样、做样都要受空气温度、湿度等因素的影响,尤其是对于低沸点的乙醛(沸点20.8℃)来说,更比较困难。一般来说,测定化合物中水分含量的方法有以下几种:①卡尔·费休法;②色谱法;③重量法。因乙醛沸点太低,不能应用重量法。
浩瀚色谱（山东）应用技术开发有限公司为此进行了卡尔·费休法和色谱法的试验,以确定乙醛中水分的测定方法。

Usually, it is difficult to accurately determine the moisture content in chemical products, because both sampling and sample preparation are affected by factors such as air temperature and humidity, especially for acetaldehyde with a low boiling point (boiling point 20.8 °C). , more difficult. Generally speaking, there are several methods for determining the moisture content in compounds: ① Karl Fischer method; ② Chromatography; ③ Gravimetric method. Because the boiling point of acetaldehyde is too low, the gravimetric method cannot be used.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has carried out Karl Fischer method and chromatography test to determine the determination method of moisture in acetaldehyde.
