hplc column selection
1. Column tube specifications: including column length and inner diameter, common specifications include 150mm x 4.6mm. The longer the column length, the better the separation effect, but it will increase the column pressure and analysis time. A shorter column length (such as 50mm) is usually sufficient to provide good separation efficiency.
2. Particle size: Particle size affects separation speed and column efficiency. Smaller particle sizes (such as 1.8 μ m, 3.5 μ m) can provide higher column efficiency, but require higher column pressure. 5 μ m filler is a commonly used choice for analysis.
3. Pore size: Pore size affects the retention characteristics of the sample, and common pore sizes include 60 Å, 120 Å, and 300 Å. Small molecules are suitable for pore sizes of 80-120 Å, while large molecules are suitable for pore sizes of 300 Å.
4. Shape of packing particles: Spherical particles can reduce column pressure and prolong column life in high viscosity mobile phases.
5. Specific surface area: Specific surface area is related to particle size and pore size, which affects the contact area between the sample and the filler, thereby affecting the separation effect.
6. Chemical properties: including silicone matrix, polymer matrix, carbon loading, bonding phase, and end capping. Different chemical properties affect the separation selectivity and stability of chromatographic columns.
7. pH Range: The pH range of a chromatographic column affects its performance under specific conditions.
8. Column efficiency: It is usually measured by the theoretical number of trays and is an important indicator for evaluating the efficiency of chromatographic columns.
9. Separation degree: Separation degree is an indicator of the separation performance of a chromatographic column.
10. Peak symmetry: Peak symmetry is an indicator that describes the degree of symmetry of chromatographic peaks, and a symmetrical peak shape helps improve the accuracy of analysis.
