COSMOSIL C18-PAQ

Reversed Phase / For aqueous conditions

COSMOSIL 5C18-PAQ is designed to offer superior retention of polar compounds and excellent reproducibility in highly aqueous mobile phases, even in 100% aqueous.

COSMOSIL 5C18-PAQ
Silicagel high purity porous spherical silica
Average particle size 5µm
Average pore size approx. 120Å
Specific surface area approx. 300m2/g
Stationary phase polymeric octadecyl group
End capping treatment near-perfect treatment
Carbon content approx. 11%

 

Stable Performance under 100% Aqueous Conditions

The figure shows the stable retention on COSMOSIL 5C18-PAQ while the retention on conventional ODS significantly decreases after 1 hour flow of 100 % aqueous mobile phase.

Application

Organic acid analysis
