Determination of Monomethylamine by Gas Chromatography
Detection of Monomethylamine by Gas Chromatography Details:

Name: Amine special column

Specifications: 2m*3mm

Model: HH-SJNH2

Granularity: 60-80 mesh

Application: Determination of ammonia, monomethylamine, dimethylamine, trimethylamine


Monomethylamine: It is a colorless gas under normal temperature and pressure, and its specific gravity is 1.07 times that of air. It is flammable, explosive, and has a strong irritating ammonia-like odor. Alkaline degree is stronger than ammonia. Generally pressurized into liquid, prepared into aqueous solution, alcoholic solution or hydrochloride for storage or transportation. Monomethylamine has a wide range of industrial uses, mainly used as medicine (caffeine, ephedrine, etc.), pesticides (carbaine, dimethoate, insecticide, etc.), dyes (alizarin intermediates, anthraquinone intermediates, etc. ), explosives and fuels (water-gel explosives, monomethyl hydrazine, etc.), surfactants, accelerators, and raw materials for rubber auxiliaries, photographic chemicals and solvents.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has studied the method of rapid separation and determination of monomethylamine, dimethylamine and trimethylamine by gas chromatography HH-SJNH2 column. The results show that the standard curves of monomethylamine, dimethylamine and trimethylamine have good linearity with FID detector and external standard method, and the correlation coefficients are 0.998 3, 0.997 5 and 0.996 6, respectively.
