描述

一般說明

Chromolith^® SemiPrep RP-18封端HPLC色谱柱非常适合从分析到半制备柱的直接放大。这是因为与填充5 μm颗粒的半制备柱相比，它们在较低的操作压力下提供更快的样品吞吐量。Chromolith^® SemiPrep 10 mm内径色谱柱结合了高分离速度和优异的性能。这使得它们成为10 mm内径（甚至21.2mm内径）颗粒柱的完美替代品。它们具有与Chromolith^®分析柱相同的双峰多孔硅棒结构，内径为4.6 mm。其大孔直径为2 μm，中孔直径为13 nm。这种组合大大减少了分离时间，同时提高了效率。

革命性的整体二氧化硅具有独特的大孔和中孔组合，实现了：
—在极低的柱背压下快速分离
—高矩阵公差，通过简化工作流程节省时间和成本
—色谱柱寿命延长节省了成本
