401 deoxygenation column
401 deoxygenation column Detailed information:

Specifications: 3m*3mm, 3m*1/8, 3m*4mm
Model: 401
Application: Removal of trace O2 in gas separation

In the determination and analysis of industrial oxygen, the national standard GB/T 3863-1995 "Industrial Oxygen Determination and Analysis Method" is used to absorb oxygen in a copper ammonia solution, and the oxygen content is calculated according to the residual gas volume after absorption, but there is an analysis. The operation is complicated, the accuracy is poor, and it is not suitable for the determination of the oxygen concentration in the liquid oxygen of the large air separation device.
Oxygen and argon have similar physical properties and are difficult to separate on the column. The obtained peak is usually a mixed component and cannot be quantified. Therefore, oxygen-argon separation is a major problem in chromatographic separation. In the national standard GB/T 14605-93 "Determination of Trace Argon, Nitrogen and Helium in Oxygen Gas Chromatography", the deoxidation column (401 deoxidizer) is used to remove oxygen first, and then the detected components are argon, nitrogen and helium. After separation by the chromatographic column, it enters the detector to achieve the purpose of measuring and analyzing components such as argon and nitrogen.
