High-Performance Core-Shell Columns for UHPLC and HPLC
Core-Shell Technology for Enhanced Column Efficiency
In core-shell particles, analyte molecules pass through a thin porous shell surrounding a solid non-porous core. This structure significantly reduces diffusion within the particle compared to fully porous particles, resulting in sharper peaks and higher theoretical plate numbers
Advantages of Core-Shell Packing Material
●Excellent particle size distribution minimizes multiple-path diffusion, enhancing efficiency and peak sharpness.
●A 2.6 μm core-shell particle delivers a comparable number of theoretical plates to that of a sub-2 μm fully porous particle, but with the backpressure of a 3 μm fully porous column.
●The number of theoretical plates is increased by minimizing diffusion within the particle.
