601 碳分子筛柱应用之一氧化碳CO2测定的详细资料

碳分子筛柱应用之一氧化碳CO2测定
碳分子筛柱应用之一氧化碳CO2测定 详细信息：

名称：碳分子筛
规格：2m*3mm
型号：601
应用： 丙烯中微量一氧化碳、二氧化碳含量测定

聚丙烯装置生产中对丙烯原料中一氧化碳、二氧化碳含量控制较为严格,特别是使用茂金属催化剂后,对丙烯中的一氧化碳、二氧化碳含量要求提升到uL/m3级,而目前所用的分析方法GB/T 3394-2009《工业用乙烯、丙烯中微量一氧化碳、二氧化碳和乙炔的测定气相色谱法》低检出限只能达到mL/m^3级,完全不能适应目前更高的要求。
浩瀚色谱（山东）应用技术开发有限公司通过对分析方法实验条件的改造优化,以及试验摸索,建立了可检测丙烯中微量一氧化碳、二氧化碳分析方法,结果表明:经优化后的方法测定丙烯中一氧化碳与二氧化碳低检出限分别可达5uL/m^3与18uL/m^3,方法3次重复测定被测组分的相对标准偏差均小于12.85%,数据的精密度良好,可满足聚丙烯装置试用茂金属催化剂对丙烯检测的技术要求。

Carbon molecular sieve column application carbon monoxide CO2 determination
Carbon molecular sieve column is used for the determination of carbon dioxide CO2. Details:

Name: Carbon Molecular Sieve
Specification: 2m*3mm
Model: 601
Application: Determination of trace carbon monoxide and carbon dioxide content in propylene

In the production of polypropylene plants, the control of carbon monoxide and carbon dioxide content in propylene raw materials is relatively strict, especially after the use of metallocene catalysts, the requirements for carbon monoxide and carbon dioxide content in propylene are increased to uL/m3 level, and the current analysis method GB/T The minimum detection limit of 3394-2009 "Determination of Trace Carbon Monoxide, Carbon Dioxide and Acetylene in Industrial Ethylene and Propylene by Gas Chromatography" can only reach the mL/m^3 level, which cannot meet the current higher requirements at all.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established an analytical method that can detect trace amounts of carbon monoxide and carbon dioxide in propylene through the modification and optimization of the experimental conditions of the analytical method and experimental exploration. The minimum detection limits of carbon dioxide can reach 5uL/m^3 and 18uL/m^3, respectively. The relative standard deviations of the tested components of the method for three repeated determinations are less than 12.85%, and the precision of the data is good, which can meet the trial use of polypropylene devices. The technical requirements of metallocene catalyst for the detection of propylene.
