These columns are packed with Daicel’s coated polysaccharide-based chiral stationary phases (CSPs) which are manufactured by physically coating the polysaccharide derivatives onto silica matrices. Due to this manufacturing process, a choice of mobile phase components is typically narrower than with immobilised columns in order to minimise damage to the CSPs.

The HPLC analytical guard cartridges need to be mounted in a cartridge holder to be connected to the analytical column. For maximum lifetime, analytical columns should be used in series with an appropriate guard cartridge or column. Both formats are available with the packing material to match the protected column.

When a material is in a state that the temperature and the pressure exceed the critical point, it becomes a supercritical fluid. In this phase, the density of gas and liquid becomes the same.

CHIRALPAK® QN-AX and CHIRALPAK® QD-AX are enantioselective weak anion-exchange (AX) HPLC columns. The chiral selectors for CHIRALPAK® QD-AX and CHIRALPAK® QN-AX anion exchange phases are based on complementary quinine (QN) and quinidine (QD) derivative selectors bonded to high efficiency 5 µm diameter spherical silica. The structure of these selectors is such that a tertiary amine is located in a three-dimensional cleft surrounded by additional hydrogen binding sites and a large aromatic group. This combination provides excellent separations of chiral acids.

CROWNPAK® CR(+) and CR(-) contain a chiral crown ether as a chiral selector, which is coated onto a 5 µm silica support. CROWNPAK® selectors are mainly used to separate chiral amino acids and other small molecules with primary amine groups. The elution order of the enantiomers can be reversed when necessary.

These protein-based columns are suitable for separation of basic, acidic and non-protolytic compounds. These columns function entirely in the reversed phase chromatographic mode, using buffers with low organic modifier content and at moderate pH values.

For the separation of acidic chiral compounds containing carboxylic, phosphonic, phosphinic, phosphoric or sulphonic acid groups. In some cases weakly acidic compounds, such as phenols, can also be separated.

These columns allow chromatographers to employ essentially any organic solvent as mobile phase to develop methods for the most challenging separations. These columns are available in a variety of particle sizes and offer great speed and column resolving power. Columns packed with 3 µm CSPs offer high speed separations and a reduction in analysis time and cost per sample. Columns, packed with 3 µm particles, may be used in conventional HPLC units without significant loss in performance, even with the smaller column dimensions.
