MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge, 5 μm Particle Size
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Diol Supelguard Cartridge, 5 μm Particle Size
LC-Diol columns can be used to separate proteins by gel filtration chromatography.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Si Supelguard Cartridge Kit, 5 μm Particle Size
A typical mobile phase used with normal-phase silica columns consists of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small percentage of more polar solvent.
