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.

Column type: HPLC column, CHIRALPAK® MSA, Stainless steel, Ø int.: 4,00 mm, Length: 50 mm, Particle size: 5 µm

Supplier: DR MAISCH

One of the most versatile chiral column available for normal phase HPLC. Use on compounds with aromatic, amide, carbamate, ester groups, alkyl amines, and compounds with multiple stereogenic sites.

Supplier: CHIRAL TECHNOLOGIES

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.

Supplier: MP Biomedicals

DL-Threonine is an essential α - amino acid classified as polar which has two chiral centers. In plants and micro-organisms, threonine is synthesized from aspartic acid via aspartyl - semialdehyde and homoserine.

Supplier: AAT BIOQUEST

Lactic acid is chiral and has two optical isomers: L-lactic acid and D-lactic acid.

Supplier: CHIRAL TECHNOLOGIES

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.

Supplier: MACHEREY-NAGEL

These glass plates with a special layer are used for TLC enantiomer separations (e.g. amino acids, thiazolidine derivatives, dipeptides, lactones, α-hydroxycarboxylic acids).

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.

Supplier: CHIRAL TECHNOLOGIES

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.
