Average particle size: 3µm, 5µm Average pore size: 120 Å Surface area: 340 m2/g Carbon contents: 17 % Bonded phase: C18 (Octadecyl) End-capping: Yes USP category: L1 Range of pH: pH 2 – pH 9 
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.
