應用：工業(yè)用甲醇中痕量三甲胺含量的測定 氣相色譜質譜聯用法

以煤為原料生產甲醇時，由于在高溫高壓下進行，會發(fā)生一定的副反應，生成三甲胺(TMA)等副產物。雖經過精餾，但在精甲醇中仍存在一定量(1O*10-9-150*1O-9)的TMA。TMA是造成甲醇制丙烯(MTP)催化劑使用壽命短和失活的毒物，因此應嚴格控制甲醇中的TMA含量，這對MTP催化劑極其重要。


浩瀚色譜（山東）應用技術開發(fā)有限公司采用毛細管柱,用氮磷檢測器(NPD)和內標法建立了工業(yè)甲醇中痕量三甲胺(TMA)的測定方法,該方法相關線性系數達到99.9%.高惰性襯管可解決吸附問題,可以快速,準確地測量工業(yè)甲醇中的TMA含量,為下游產品的生產提供操作數據.

Analysis of Trace Trimethylamine in Industrial Methanol by Gas Chromatography
Analysis of Trace Trimethylamine in Industrial Methanol by Gas Chromatography Details:

Name: capillary column
Fixative: Alkaline-deactivated polyethylene glycol
Specifications: 30m*0.25mm*0.25um
Model: HH-WAX
Application: Determination of trace trimethylamine content in industrial methanol by gas chromatography-mass spectrometry

When using coal as raw material to produce methanol, due to the high temperature and high pressure, certain side reactions will occur, resulting in trimethylamine (TMA) and other by-products. Although it has been rectified, there is still a certain amount of TMA (1O*10-9-150*1O-9) in the refined methanol. TMA is a poison that causes short service life and deactivation of methanol-to-propylene (MTP) catalysts, so the TMA content in methanol should be strictly controlled, which is extremely important for MTP catalysts.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used capillary column, nitrogen phosphorus detector (NPD) and internal standard method to establish a method for the determination of trace trimethylamine (TMA) in industrial methanol, the correlation linear coefficient of the method reached 99.9% .Highly inert liner can solve the adsorption problem, can quickly and accurately measure the TMA content in industrial methanol, and provide operational data for the production of downstream products.
