工业甲醛溶液的传统分析采用理化滴定法，分析时间长，效率低下，无法满足工业生产的需要，使用受限。
关于气相色谱法分析甲醛溶液，色谱柱是一大难题，一般的色谱柱，柱效低，色谱峰拖尾，重复性差，无法准确的定量。
浩瀚色谱（山东）应用技术开发有限公司，与时俱进，研发HH-PA-II填充柱测定工业甲醛溶液，该方法简便、快速、准确度高、精密度高。
含量低的甲醇首先流出，是此柱的一大特色，保证了甲醇无覆盖，定量准确可靠。

The traditional analysis of industrial formaldehyde solution adopts physical and chemical titration method, which takes a long time and is inefficient, and can not meet the needs of industrial production and is limited in use.
As for the analysis of formaldehyde solution by gas chromatography, chromatographic column is a big problem. General chromatographic column has low column efficiency, trailing chromatographic peak, poor repeatability, and cannot be accurately quantified.
Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has developed a HH-PA-II packed column for the determination of industrial formaldehyde solution, which is simple, rapid, accurate and precise.
The low content of methanol flows out first, which is a major feature of this column, ensuring that the methanol is not covered, and the quantity is accurate and reliable.
