用電位滴定法測定工業(yè)甲醛溶液中甲醛含量的費時費力，分析時間長；傳統(tǒng)的氣相色譜法測定甲醛溶液，采用常規(guī)的色譜柱，含量低的甲醇在溶劑水后面出，定量誤差大，有時會覆蓋，無法準確的測定。
浩瀚色譜（山東）應用技術(shù)開發(fā)有限公司，與時俱進，開發(fā)出HH-PA-II工業(yè)甲醛溶液分析專用色譜柱，出峰順序為：甲醇，水分及甲醛。含量低的甲醇首先流出，峰型對稱，無覆蓋，定量準確可靠。。該方法簡便、快速、準確度高、精密度高。此款產(chǎn)品為浩瀚色譜的特色產(chǎn)品，歡迎咨詢洽談。

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.
