It is the column which made C1 (Trimethyl) group modify.
There is performance which is not in C1 conventional column, and it contributes to many analysis systems.
Develosil XG-C1 has introduced C1 (Tori methyl radical) into the inhouse high grade silica gel. (USP column code: Equivalent to L13) The retention and separation which cannot be predicted in C1 conventional column by the height of surface area and special end cap treatment are attained. It corresponds to many analysis kinds, such as a basic compound, a vitamin, and drugs, including an organic acid.
