一、毛细管分离柱气相色谱仪使用的分离柱包括填充柱、微粒填充柱、毛细管空心柱和弹性石英玻璃毛细管柱等类型.毛细管柱的出现是气相色谱仪发展中的一个重要里程碑.它的阻力小,载气流速快,柱温要求低,因而可以大幅度地增加柱长,显著地提高分离效果,特别适合于作多组分微量物质的分析.例如Quadrex公司生产的玻璃毛细管极性柱Silar 10c,长76米,理论塔板数5315/米,总塔板数可达40万.
1. Capillary Separation Column The separation column used in gas chromatography includes packed column, packed particle column, capillary hollow column and elastic quartz glass capillary column, etc. The appearance of capillary column is an important milestone in the development of gas chromatography. Small, fast carrier gas flow rate, low column temperature requirements, which can significantly increase the column length, significantly improve the separation effect, especially suitable for multi-component trace substances such as Quadrex glass capillary polar column Silar 10c, 76 meters long, the number of theoretical plates 5315 / m, the total number of plates up to 400000.
