说明

一般描述

Ascentis® Express 160 Å C30 is a high-speed, high-performance liquid chromatography column based on the wider-pore 160 Å Fused-Core® particle design to provide adequate spacing for the long-chain C30 ligands. The particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0.5 μm thick porous shell and the small overall particle size of 2.7 μm. The endcapped triacontylsilane stationary phase of the C30 provides a stable, reversed-phase packing that can be used for hydrophobic, long-chain, structural isomers such as vitamins and lipids.

Ascentis®Express 160ÅC30是一种高速高效液相色谱柱，基于更宽的孔160ÅFused Core®颗粒设计，为长链C30配体提供足够的间距。该颗粒在固体硅芯周围提供了一个由高纯度二氧化硅构成的多孔薄壳。由于0.5μm厚多孔壳中的浅扩散路径和2.7μm的小总粒径，这种颗粒设计显示出非常高的柱效率。C30的端盖三十烷硅烷固定相提供了一种稳定的反相填料，可用于疏水性长链结构异构体，如维生素和脂质。

分析说明

The target analytes include hydrophobic analytes, lipids, carotenoids, and fat soluable vitamins (A, D, E, K).

目标分析物包括疏水性分析物、脂质、类胡萝卜素和脂溶性维生素（A、D、E、K）。
