| titleOfInvention | A kind of metal porous layer open tubular column for hydrogen isotope gas analysis and preparation method thereof |
| abstract | The invention relates to the technical field of gas chromatographic analysis, in particular to a metal porous layer open tube column for hydrogen isotope gas analysis and a preparation method thereof. The porous layer open tube column adopts a stainless steel tube as the column material, and a The transition layer of the fluffy structure is further provided with a stationary phase layer on the surface layer of the transition layer. In the porous layer pipe column disclosed in the present invention, the transition layer is arranged as the anchoring layer of the stationary phase layer, which can significantly improve the problem that the stationary phase is easy to fall off due to the large difference in thermal expansion coefficient between the stainless steel cylinder and the stationary phase of the chromatographic column. , the porous layer open tubular column has excellent mechanical stability and thermal stability, is easy to install and carry, and is more conducive to the safety consideration of the hydrogen isotope gas analysis process. |
