Symmetry C18柱的骨架是高纯硅胶C18，pH 2-8。载量大、分辨率高，在中- 低pH 使用范围内通用性极佳。特别适用于要求高分辨、高载量的痕量组分制备。对于胺基类化合物，当需要使用低pH 条件、甚至甲酸体系时，峰形佳。
■精心设计填料的物理和化学性质，以确保最大容载量与最优分辨率；尤其有利于在低至中等pH条件下分离纯化可电离化合物。
■耐受低pH条件，键合相稳定牢固，柱寿命长。
■结合于OBD™制备柱设计，确保最高柱效与最长柱寿命。
■填料起始于有机硅合成，继以专利技术的表面化学修饰，所有制造工艺与过程均依从cGMP规范，确保产品的高纯品质、高优性能、与高度可靠。
By virtue of the different elution patterns of vindoline, catharanthine, vincristine and vinblastine present in the leaves of Catharanthus roseus plants, a Symmetry C18 column provided a better resolution for all of these compounds as compared with other C18 columns. The binary gradient system with a linear gradient profile, employed in a method developed using a Symmetry C18 column, gave excellent peak symmetry, resolution and reproducibility. Detection was performed at 220 nm which presented better absorptivity for these indole alkaloids giving a minimum detection limit of 0.5 microgram. Photodiode array detection was used to determine the homogeneity and purity of each compound. The described analysis is rapid and economical to perform as small amounts of solvent are consumed per analysis, and the method will find application where a large number of samples are to be analysed as, for example, in crop improvement studies where plants need to be selected regularly on the basis of alkaloid production.
