本品为无色或几乎无色的澄明液体，有刺激性特臭、能刺激鼻喉黏膜；在冷处久置易发生浑浊。
本品能与水或乙醇仔意混合。
本品含甲醛（CH2O）不得少于36.0％（g／g）。
本品中含有10％-12％的甲醇，以防止聚合。
药典中甲醛溶液的测定采用的是理化滴定法，分析时间长，效率低，无法满足生产检测的需求。浩瀚色谱研制气相色谱法测定甲醛溶液，甲醇，水分，甲醛分离良好，，结果准确。
含量低的甲醇首先流出，是此柱的一大特色，了甲醇无覆盖，定量准确。
名称：甲醛填充柱
型号：HH-PA-II
规格：2m*3mm，60-80目

This product is a colorless or almost colorless clear liquid with irritating odor and can stimulate nasal and laryngeal mucosa; Turbidity is easy to occur if it is stored in cold place for a long time.
This product can be mixed with water or ethanol.
The content of formaldehyde (CH2O) in this product shall not be less than 36.0% (g/g).
This product contains 10% - 12% methanol to prevent polymerization.
The determination of formaldehyde solution in the pharmacopoeia adopts the physical-chemical titration method, which takes a long time and is inefficient, and cannot meet the requirements of production and detection. The gas chromatographic method for the determination of formaldehyde solution, methanol, water and formaldehyde is developed by Vast Chromatography with good separation, high efficiency and accurate and reliable results.
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.
Name: Formaldehyde-filled column
Model: HH-PA-II
Specification: 2m * 3mm, 60-80 mesh
No.: 20230206007
Zuigao service temperature: 180 ° C
Welcome to consult and discuss the development of the vast chromatogram.
