HPLC Column Raptor Polar X, 90Å, 2.7 µm, 50 x 2.1 mm

Reliably analyze a wide variety of polar analytes (acidic, basic, and neutral) without time-consuming derivatization or complex ion pairing.
Switch between HILIC and ion-exchange retention modes with simple mobile phase changes and short equilibration times.
2.7 μm Raptor core-shell particles provide UHPLC-like speed and efficiency on all makes and models of LC systems.
Ideal for increasing sensitivity and selectivity in LC-MS analyses.
Storage Conditions: When not in use, Raptor Polar X columns must be kept in 100% acetonitrile. If using a buffered mobile phase, first flush thoroughly with 50:50 water:acetonitrile, then fill with acetonitrile for storage.

Note: We strongly recommend that you only order a semi-preparative or preparative column once you have evaluated the desired separation on an equivalent column on an analytical scale.
Because we cannot reuse a column or the silica within it once it leaves our facility, we cannot accept returns of large columns.
