Alumina micro diameter chromatographic column

Details of alumina micro diameter chromatographic column:



The micro packed column is divided into two types: inner diameter 1mm, outer diameter 1/16 inch and inner diameter 0.75 mm, outer diameter 0.95 mm. The former can be connected to the packed column injection system, while the latter is connected to the injection system of 0.53 mm fused silica capillary column.





Name: Al2O3 micro diameter column



Model: AL2O3



Specification: 0.7m * 1/16100-120mesh



Maximum operating temperature: 240 ° C



No.: 20221202003





Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed analytical methods for hydrocarbon impurities in polymer grade ethylene and propylene. This method uses one/Al_ 2O_ 3. The core packed micro diameter chromatographic column is an analytical column, FTD detection, one-time sample injection, external standard peak height or peak area quantification, to achieve C in the above samples_ 1～C_ 4 Total composition analysis of hydrocarbon impurities. The detection limit of the method is at least 0.5 ～ 5ppm (ml/m3), and the relative standard deviation of the results is less than 10%.
