Allsphere C8 is a fully porous silica-based HPLC column bonded with octyl (C8) groups. Offering medium hydrophobic retention, it provides a balanced alternative to C18 for analytes that elute too slowly or too strongly retained. With excellent peak shape and chemical stability, Allsphere C8 is ideal for routine reversed-phase separations in pharmaceutical, food, and environmental applications.
Allsphere C8 provides reproducible reversed-phase performance with shorter retention times – a reliable solution for daily HPLC workflows.
