Shimadzu 13X packed column wholesale Details:

Name: Packed column
Specification: 2m*3mm*4mm
Model: 13X
Application: Shimadzu GC-2010, GC-2014, GC-2030, GC-14C

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. uses H_2 as the carrier gas to determine the adsorption equilibrium constant and mass transfer coefficient of O_2 and N_2 on a 13X molecular sieve packed column by chromatography with the aid of a computer. It is proposed to calculate the adsorption equilibrium constant by the moment method with a small amount of calculation, and then estimate the total mass transfer coefficient from a single parameter in the time domain. From the experimental results and theoretical analysis, it is found that in this system, the axial diffusion contributes the most to the total mass transfer resistance, and the correlation between the axial diffusion coefficient and the operating conditions is obtained.

This column has high efficiency, good separation and accurate and reliable measurement results.
