Overview

High Performance Core-Shell Column For UHPLC/HPLC

The molecules of the target analytes pass through the fine pores in the particles in the packing material. Core-shell particles are formed around a solid non-porous core, resulting in less diffusion inside the fine pore structure. This differs from the more traditional fully porous particle. When using a core-shell column, the distribution of molecules in the peak is narrower when the target compound is eluted from the column, resulting in a greater number of theoretical plates.

Core-Shell type packing material

Conventional fully porous packing material

The effect of multiple-path diffusion is significantly reduced by improving the particle size distribution homogeneity to the highest achievable limits.
A 2.6μm core-shell packing material achieves a comparable number of theoretical plates as a Sub 2μm fully porous packing material, but with the same back-pressure as a column using 3μm fully porous packing material.
The theoretical plates are improved by reducing diffusion inside the particle.

Comparison with Products from Other Suppliers

The InertCore Plus C18 columns are subjected to rigorous internal quality control from bare silica manufacturing to inspection, resulting in superior reproducibility due to shell layer homogeneity.

Superior Reproducibility

The InertCore Plus C18 columns are subjected to rigorous internal quality control from bare silica manufacturing to inspection, resulting in superior reproducibility due to shell layer homogeneity.

High Durability

InertCore Plus C18 has high durability demonstrating that the performance for retention time, theoretical plate and symmetry factor is maintained even after 2000 continuous injections.

Suitable for Both General Purpose HPLC and UHPLC

The results of analyses performed with the InertCore Plus C18 on two different HPLC systems, under the same conditions are shown. Peak shapes are excellent in both cases and equivalent chromatograms were obtained.
