乔di Resolve GPC Columns: 5UM GPC粒子柱的图像乐动体育登录Jordi Labs最近为GPC系统开发了一种新颖的包装材料。该柱填料基于100％divinylbenzene提供增强的机械稳定性，并利用了新的合成过程，从而导致单分散聚合物柱填料。众所周知，基于粒子柱中的宽粒径分布会产生堆积密度的变化，降低柱分辨率，降低柱渗透性并产生高背压。新一代Jordi GPC柱，由单分散的100％divinylbenzene颗粒具有精确控制的颗粒直径和精细控制的孔结构提供高效率，高分离能力和较高的床稳定性。图1显示了扫描电子显微照片和5μm大孔柱填料材料的孔径。

Mixed bed Resolve columns allow for separation over the molecular weight range from 200 to 3,000,000 g/mol (PS equivalent) with a coefficient of determination (R²) of 0.999. For higher molecular weights, Jordi Labs offers its Jordi Resolve DVB 13 μm columns. New generation Jordi Resolve columns (7.8 mm x 300 mm) are produced to allow separation over the molecular weight range from 500 to 12,000,000 g/mol (PS equivalent).

由于难以防止样品列相互作用，因此在基于尺寸的分离领域中，水应用在基于尺寸的分离领域带来了重大挑战。乔迪（Jordi）在水性移动阶段提供三列化学成分，包括：Jordi Resolve Xstream，Jordi Resolve Anion和Jordi Resolve Cation。
