一般說明
Chromolith®高分辨率RP-18封端柱具有直径1.15 μm的大孔隙,色谱柱效率超过140,000塔板/米。中孔为15 nm(150 Å),表面修饰为带有完整封端的十八烷基硅烷。Chromolith®高分辨率RP-18封端柱属于USP L1类。柱效率可与2.7至3μm粒径全孔隙颗粒柱相媲美。Chromolith®高分辨率RP-18封端柱非常适用于LC-MS应用。
柱长100 mm,内径4.6 mm,是所有HPLC系统的高分辨率分离的不二之选。
这种突破性硅胶整体以其独特的大孔和中孔结构组合实现了以下功能:
—在极低的柱背压下实现快速分离
—具有高容忍度基质,简化工作流程,同时省时省钱
—延长柱使用寿命,实现成本节约
—连接柱、流动梯度及使用粘度较高的移动相
Chromolith®高分辨率RP-18封端5-4.6保护小柱(3件)[1.52025]和Chromolith®保护小柱支架5 mm x 4.6 mm[1.52032]
。Chromolith®柱耦合器可通过串联多个柱(高达100,000板/柱)来显著提高Chromolith®柱的分离效率。[1.51467]

Praziquantel Determination in Aquarium Water - Learn how the use of a Chromolith® monolithic silica column allows simplification of sample preparation.
Folic acid or folate is classified as a B vitamin (B9). Folic acid is synthetically produced, and used in fortified foods and supplements. Folate is converted by humans to dihydrofolate (dihydrofolic acid), tetrahydrofolate (tetrahydrofolic acid), and other derivatives, which have various biological activities.
This application illustrate how Rutin can be determined in skin cream samples using a monolithic Chromolith® HighResolution RP-18 endcapped column with UV detection.
