乔di Resolve GPC Columns: 5um GPC粒子柱的图像乐动体育登录Jordi Labs最近开发了一种用于GPC系统的新型包装材料。该柱包装基于100％二乙烯基苯，提供增强的机械稳定性，并利用新的合成方法，从而导致单分散的聚合物塔填料。众所周知，粒子柱中的宽粒度分布产生填充密度的变化，降低柱分辨率，降低了柱渗透性并产生高背压。使用精确控制的粒径100％二乙烯基苯颗粒制备的新一代Jordi GPC柱，具有精确控制的粒径和细腻控制的孔隙结构，提供高效率，高分离能力和低背压，具有更高的床稳定性。扫描电子显微照片和5μm大孔柱填充材料的粒度分布，具有10°孔径，如图1所示。清楚地看到均匀的尺寸分布和完美的球形形状。

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).

由于防止样品柱相互作用难以，水性应用在基于大小的分离领域具有显着挑战。jordi为含水移动阶段提供三个专栏化学品，包括：jordi解决xstream，jordi解决阴离子和jordi解决阳离子。
