Celeris™ PEI - 5 µm, 100 Å, 100 mm x 3 mm

The Celeris™ polyethylenimine (PEI) achiral SFC phase has nearly three times more amino groups than traditional amino phases. The stationary phase is a modified polymer which includes several tertiary amine groups in the skeleton of the phase. This unique selectivity allows faster elution to give high quality separations in shorter times.
