Celeris Achiral SFC Columns from Regis
The Celeris family of achiral stationary phases has been specifically designed for SFC separations, delivering high capacity, broad selectivity, excellent peak shapes, and reproducible performance over long column lifetimes. Celeris high performance phases provide rapid separation and recovery of purified components at a lower price than competitor offerings, enabling use of larger column sizes to reduce the number of purification cycles required to achieve purity of the batch.
Celeris Ethyl Pyridine - Celeris 2EP and 4EP deliver high performance separations comparable to other ethyl pyridine phases
Celeris Arginine - Benefit from an achiral SFC phase with mixed-mode type of selectivity
Celeris Amino - Achieve a higher degree of polar selectivity over the Ethyl Pyridine phases
Celeris PEI - Unique phase for high quality separations in shorter times by faster elution
Celeris Silica - An ultra-pure, metal-free silica phase that offers great polar selectivity
Celeris Diol - Offers alternative selectivity to silica columns, often with increased retention

Specifications
Celeris Ethyl Pyridine
Ethyl pyridine phases are the workhorse phases for preparative and process scale SFC purifications. Celeris 2EP (2-ethyl pyridine) and 4EP (4-ethyl pyridine) media is designed to be highly reproducible based on tight product specifications and low metal content. Celeris 2EP is especially well-suited for separation of acidic compounds and exhibits broad selectivity towards a variety of other compound types. The Celeris 4EP phase offers alternate selectivity to the 2EP phase. Celeris 2EP and 4EP SFC columns deliver high performance separations comparable to competing ethyl pyridine phases at a much lower price.
Celeris Arginine
The arginine (ARG) achiral SFC phase is a silica surface modified with the amino acid arginine and exhibits both acidic and basic functionality. The ARG phase has a strong affinity to hydrophilic compounds and offers a mixed-mode type of selectivity compared to other SFC phases.
Celeris Amino
Celeris Amino columns are packed with a traditional propyl-amine phase bonded to 100 Å silica. This offers a high degree of polar selectivity over traditional silica or Ethyl Pyridine phases, allowing a high degree of retention for polar amine compounds.
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.
Celeris Silica
The Celeris Silica achiral SFC phase is an ultra-pure, metal-free silica particle that offers great polar selectivity.
Celeris Diol
The Celeris Diol achiral SFC phase is a traditional diol phase bonded to 100 Å silica and offers alternate selectivity to silica columns, often with increased retention. The separation mechanism of the diol phase is hydrogen bonding interactions between diol groups and polar compounds.
