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.
