C8 is the most commonly used column type following C18. C8 is well suited for the separation of many compounds which are too strongly retained on C18 phases or require greater retention than C4. The moderate hydrophobicity makes it suitable for separation of relatively hydrophobic samples. It is suitable for separation of pharmaceuticals, organic chemicals and biologicals.
