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.
