General description
CHIROBIOTIC® T and T2 have teicoplanin as the chiral selector. They offer unique selectivity for a number of classes of molecules, specifically underivatized α, β, γ and cyclic amino acids, N-derivatized amino acids, hydroxy-carboxylic acids, acidic compounds including carboxylic acids and phenols, small peptides, neutral aromatic analytes and cyclic aromatic and aliphatic amines. Separations normally obtained on a chiral crown ether or ligand exchange-type CSPs are also possible on the CHIROBIOTIC® T and T2, but in much simpler mobile phases, like water-alcohol. In addition, all of the known beta-blockers (amino alcohols), and dihydrocoumarins have been resolved. CHIROBIOTIC® T and T2 differ in their bonding chemistry and the pore size of the support particle, giving them different selectivity and preparative capacity.
• Bonded phase: Teicoplanin
• Operating pH range: 3.8 - 6.8
• Particle diameter: 5, 10 or 16 μm
• Pore size: 100 Å (CHIROBIOTIC® T) or 200 Å (CHIROBIOTIC® T2)

高分子化合物又称高分子(聚合物),高分子是由分子量很大的长链分子所组成,高分子的分子量从几千到几十万甚至几百万。而每个分子链都是由共价键联合的成百上千的一种或多种小分子构造而成。高分子的分类有多种,按来源可分为天然高分子、天然高分子衍生物、合成高分子三大类;根据用途则可分为合成树脂和塑料、合成橡胶、合成纤维等;按热行为可分为热塑性和热固性聚合物;按主链结构可分为碳链、杂链、和元素有机三类;另外根据工业产量和价格还可分为通用高分子、中间高分子、工程塑料以及特种高分子等等。
