XR Series

Shim-pack XR columns have a 2.2µm particle size optimized for high resolution at elevated flow rates without extreme high pressure.  Under many analysis conditions, pressure may not exceed 35 MPa/350 bar/5000 psi, so ultrafast analysis can be comfortably performed on a standard HPLC system.  The XR column family is made from silica particles of uniform size distribution, resulting in rugged column performance, and providing excellent peak shapes, durability, and longevity.
