J´Sphere

J'Sphere™ HPLC columns manufactured by YMC™ are octadecyl phases with various content of C18 groups at the silica surface, to produce three different J´sphere ODS packings with graduated hydrophobicity or polarity. The stepwise decrease of hydrophobicity in J´sphere ODS-H80, M80 and L80 series is accompanied by an opposite increase of the H-bonding capacity.
