COSMOCORE 2.6PBr Core Shell UHPLC Columns

COSMOCORE (2.6 μm Core Shell Particle)

• Separate hydrophilic compounds in reversed-phase conditions
• Retain hydrophilic compounds longer than C18
• Greater sample loading capacity than HILIC
• High performance similar to sub-2 µm particles with lower back pressure

Core-shell particles consist of a nonporous core inside a porous shell. By using these core-shell particles, one can achieve sharper peaks compared to fully porous silica gel particles of the same diameter.

Compared to fully porous particles, core-shell particles have a more uniform particle diameter therefore, core-shell particles can be packed in the column more uniformly to minimize sample diffusion.

• Ultra-high performance LC results with conventional HPLC equipment
• Same number of theoretical plates as sub-2 µm columns with half the back pressure
• Increased loading capacity
• Excellent pH stability (1.5-10)
