詳細介紹
Symmetry C18柱的骨架是高純硅膠C18，pH 2-8。載量大、分辨率高，在中- 低pH 使用范圍內通用性。特別適用于要求高分辨、高載量的痕量組分制備。對于胺基類化合物，當需要使用低pH 條件、甚至甲酸體系時，峰形佳。
產品技術與性能，為硅膠基質的C18和C8色譜柱樹立了新的行業(yè)標準
■精心設計填料的物理和化學性質，以確保容載量與分辨率；尤其有利于在低至中等pH條件下分離純化可電離化合物。
■耐受低pH條件，鍵合相穩(wěn)定牢固，柱壽命長。
■結合于OBD™制備柱設計，確保柱效與最長柱壽命。
■填料起始于有機硅合成，繼以技術的表面化學修飾，所有制造工藝與過程均依從cGMP規(guī)范，確保產品的高純品質、高優(yōu)性能、與高度可靠。
Symmetry C18 column: a better choice for the analysis of indole alkaloids of Catharanthus roseus
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.
