COSMOCORE (2.6 μm Core Shell Particle)
Nacalai Tesque COSMOCORE 2.6C18 Analytical UHPLC Column, 2.6µm, 90Å, 3mm I.D. x 150mm Length, 1/Pk
Product Number: 12602-21
- 2.6 µm Core Shell Particle
- Increased loading capacity
- Excellent pH stability (1.5-10)
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)
