CERI L-column ODS Columns

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.
