用电位滴定法测定工业甲醛溶液中甲醛含量的费时费力，分析时间长；传统的气相色谱法测定甲醛溶液，采用常规的色谱柱，含量低的甲醇在溶剂水后面出，定量误差大，有时会覆盖，无法准确的测定。
浩瀚色谱（山东）应用技术开发有限公司，与时俱进，开发出HH-PA-II工业甲醛溶液分析专用色谱柱，出峰顺序为：甲醇，水分及甲醛。含量低的甲醇首先流出，峰型对称，无覆盖，定量准确可靠。。该方法简便、快速、准确度高、精密度高。此款产品为浩瀚色谱的特色产品，欢迎咨询洽谈。

The determination of formaldehyde content in industrial formaldehyde solution by potentiometric titration is time-consuming and laborious, and the analysis time is long; Traditional gas chromatography is used to determine formaldehyde solution. Conventional chromatographic column is used. Methanol with low content exits behind solvent water, which has large quantitative error and sometimes covers, and cannot be accurately determined.
Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has developed a special column for the analysis of industrial formaldehyde solution of HH-PA-II, with the peak sequence of methanol, water and formaldehyde. Methanol with low content flows out first, with symmetrical peak pattern, no coverage, and accurate and reliable quantification. This product is a characteristic product of the vast spectrum. Welcome to consult and negotiate.
