Celeris™ PEI

Celeris™ polyethylenimine (PEI) columns are packed with a modified polymer, which includes several tertiary amine groups in the skeleton of the phase. The phase has nearly three times more amino groups than traditional Amino phases. This provides unique selectivity and allows for faster elution to give high quality separations in shorter times.

The Celeris family of achiral stationary phases has been specifically designed forSupercritical Fluid Chromatography (SFC) separations, delivering high capacity, broad selectivity, excellent peak shapes, and reproducible performance over long column lifetimes. SFC provides a greener alternative to High-Performance Liquid Chromatography (HPLC) separation of complex samples containing a range of different functional groups and polarities. SFC provides better resolution, faster separation, and higher sample throughput compared to HPLC. However, these achiral columns are optimized to work with both the high pressures of SFC and HPLC systems.

Celeris high performance phases provide rapid separation and recovery of purified components at a lower price than competitor offerings, enabling the use of larger column sizes to reduce the number of purification cycles required to achieve purity of the batch.
