名稱：胺專用柱

規(guī)格：2m*3mm

型號：HH-SJNH2

粒度：60-80目

應用：氨，一甲胺，二甲胺，三甲胺的測定


一甲胺：常溫常壓下為無色氣體，比重為空氣的1.07倍。易燃、易爆、有強烈刺激性氨樣臭味。堿性程度較氨強。一般加壓成液體、制備成水溶液、醇溶液或鹽酸鹽進行貯存或運輸。一甲胺有廣泛的工業(yè)用途，主要用作醫(yī)藥(咖啡因、麻黃素等)，農(nóng)藥(西維因、樂果、殺蟲脒等)，染料(茜素中間體、蒽醌系中間體等)，炸藥及燃料(水膠炸藥、一甲肼等)，表面活性劑、促進劑、以及橡膠助劑、照相化學品和溶劑等的原料。

浩瀚色譜（山東）應用技術開發(fā)有限公司研究了采用氣相色譜HH-SJNH2柱快速分離測定一甲胺、二甲胺、三甲胺的含量的方法。結果表明,采用FID檢測器、外標法直接進樣,一甲胺、二甲胺、三甲胺的標準曲線線性良好,相關系數(shù)分別達0.998 3、0.997 5、0.996 6。

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.
