New and Innovative Immobilised Chiral Polysaccharide Phase

Nov 10 2020 Read 384 Times

YMC has extended its chiral portfolio consisting of immobilised and coated polysaccharide phases with the introduction of the next immobilised CHIRAL ART phase! The new CHIRAL ART Cellulose-SZ offers a new chiral selector. The innovative immobilised chiral selector is cellulose tris(3-chloro-4-methylphenylcarbamate). To date this chiral stationary phase (CSP) has only been available as a coated type from traditional suppliers (e.g. OZ or Cellulose-2).

This new immobilised version provides unrestricted use in NP-, RP- or SFC mode and offers a complementary selectivity of other CHIRAL ART phases. Notably a broader range of different sample solvents is possible. Many substances are inadequately soluble in solvents used for NP mode and solvents such as THF, DMF, DMSO or dichloromethane have to be removed, even in trace concentrations when using coated phases. In contrast, the immobilised CHIRAL ART Cellulose-SZ phase offers full compatibility and therefore much more flexibility.

CHIRAL ART Cellulose-SZ is (initially) available with 3 and 5 µm for analytical and (semi) preparative applications. In common with the other YMC chiral immobilised phases, CHIRAL ART Amylose-SA, Cellulose-SB, Cellulose SC and Cellulose-SJ, CHIRAL ART Cellulose-SZ ensures robust analyses. All CHIRAL ART phases have the same YMC silica base and the YMC-developed coating or bonding technology in common, while their chiral selectivities are quite different. The excellent lot-to-lot reproducibility for which YMC is well known, guarantees reliable results e.g. for QC purposes. CHIRAL ART columns are not only very long-lasting, but also more attractively priced.
