Chiral Technologies: CHIRALCEL

 

Daicel CHIRALCEL columns from Chiral Technologies are traditional coated cellulose phases, predecessors to the newer generation of immobilised phases. They are based on a spherical high quality silica support on to which the cellulose chiral selector is physically coated. This necessitates careful selection of solvents.

 

Columns with 3, 5 and 10um particle sizes and with analytical, semi-preparative and preparative dimensions are available. In addition, columns packed specifically for SFC applications are available.

 

The following nomenclature is used for the various series of CHIRALCEL phases.

Phase type series Eg
Traditional 10um phases -

 

e.g. OD, OJ

High resolution 5um phases

H series

e.g. OD-H

High resolution 5um phases for reversed-phase

  RH series 

e.g. OD-RH

High resolution 5um phases for SFC     

H SFC

e.g. OD-H SFC

Ultra fast 3um phases

3 series

Ultra fast 3um phases for reversed-phase

3R series

  

In addition to the well established OD and OJ phases and the newer OX and OZ chlorinated phases, a range of complementary cellulose based CHIRALCEL phases are available, including OA, OB, OC, OF, OG and OK.
