MG II is the next-generation packing material developed from the MG type, and offers the highest retention and separation performance among CAPCELL PAK. Thanks to the latest technology, it successfully seals silanol groups to the world's highest level.
Hydrophobicity and surface polarity parameters of Shiseido columns
Latest standard brand of CAPCELL PAK
MG II and MG show similar selectivities towards various compounds. These are designed to cover a wide range of substances, from low- to high-polarity ones. MG II, in addition, shows excellent peak shapes for basic compounds (e.g. amitriptyline) in neutral mobile phase conditions.
