ChiroSil® Crown Ether Phases

ChiroSil® RCA(+) and SCA (-) are proven chiral stationary phases (CSPs) for amino acid chiral analysis. Chirosil® RCA (+) and SCA (-) have (+) or (-)-(18-Crown-6)-tetracarboxylic acid as a chiral selector, which is bonded to the silica support. The ChiroSil® CSP is manufactured for use in high-performance liquid chromatography (HPLC).

Amino Acid Chiral Analysis

• ChiroSil® columns are ideal for the separation of chiral compounds containing almost all primary amino groups and natural and unnatural amino acids and their derivatives.
• This CSP offers excellent performance, high efficiency, and reproducibility.
• ChiroSil® columns are packed at 5,000 psi (~345 bar) for efficient run times.

Extreme Performance

• The ChiroSil® stationary phase delivers long life and high reliability due to covalent bonding.
• Change the elution order if necessary by selecting ChiroSil® RCA (+) or ChiroSil® SCA (-) column.
• ChiroSil® works with conventional and extended solvent ranges.

Readily Available

• ChiroSil® pre-packed columns are available in analytical dimensions.
• This CSP is available in 5 and 10 µm particle size in commonly used column sizes. Custom column dimensions are available per agreed specification.
• Bulk quantity purchases can be provided.
