Established, high-performance standard C18 column
L1: - Octadecyl silane chemically bonded to porous or non-porous silica or ceramic micro-particles, 1.5 to 10 μm in diameter, or a monolithic rod.
In 1990, L-column ODS was introduced as a column whose secondary interaction with the residual silanol groups was eliminated by a new end-capping method using high-temperature silylation. At the time, the performance of L-column ODS was far superior to that of existing C18 columns, and it became a pioneer of the new-generation end-capping method.
