工業(yè)甲醛溶液的傳統(tǒng)分析采用理化滴定法，分析時(shí)間長(zhǎng)，效率低下，無法滿足工業(yè)生產(chǎn)的需要，使用受限。
關(guān)于氣相色譜法分析甲醛溶液，色譜柱是一大難題，一般的色譜柱，柱效低，色譜峰拖尾，重復(fù)性差，無法準(zhǔn)確的定量。
浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司，與時(shí)俱進(jìn)，研發(fā)HH-PA-II填充柱測(cè)定工業(yè)甲醛溶液，該方法簡(jiǎn)便、快速、準(zhǔn)確度高、精密度高。
含量低的甲醇先流出，是此柱的特色，保證了甲醇無覆蓋，定量準(zhǔn)確可靠。

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.
