◆ High-purity spherical silica with excellent mechanical properties

◆ Suitable for normal-phase mode separations

◆ Due to the abundance of silanol groups on the surface, SIL columns (i.e., silica columns) offer superior separation performance for basic compounds

◆ Compared to similar columns, it features a wider pH range, with a tolerance of 1.5–8.5

 



Various specifications available

 (Alternative packing materials with particle sizes of 15, 20, and 50 μm are also available; please contact us for further inquiries)
