配比：載體：固定液=100:10
型號：10%PEA/401
應(yīng)用：工業(yè)乙酸甲酯測定

乙酸甲酯是醋酸裝置的產(chǎn)品之一,其含量的測定采用容量法。由于容量法測定時,樣品中含有乙酸、甲酸甲酯、甲酸等組份,這些組份相互影響,造成測定的乙酸甲酯含量比實際含量高,誤差大,難于滿足生產(chǎn)要求。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司通過大量實驗,將乙酸甲酯含量測定方法改為氣相色譜法,解決了用容量法測定乙酸甲酯含量誤差大的問題。

High column efficiency, good separation, good separation of water, methanol and methyl acetate, symmetrical peak shape, satisfactory results.

Methyl acetate is an important organic chemical raw material and chemical product, with many excellent qualities, such as low boiling point, strong solubility, and has passed the international SGS environmental protection certification, in line with the European and American ROHS directives, as a green environmental protection organic solvent. To replace acetone, methyl ethyl ketone, ethyl acetate, cyclopentane, etc., it is mainly used in resins, coatings, inks, paints, adhesives, solvents required in the leather production process, polyurethane foam foaming agents, Tianna water, etc., has been gradually It has developed into an important basic organic chemical raw material.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. changed the determination method of methyl acetate content to gas chromatography through a large number of experiments, which solved the problem of large error in the determination of methyl acetate content by volumetric method.
