L-column series

Column developed in pursuit of convenience and high performance

L-column series is the column for reversed-phase high-performance liquid chromatography (RP-HPLC) that enabled separation only by hydrophobic interaction because of inhibition of the secondary interaction with residual silanol groups and metal impurities. In 1990, the new end-capping method using high-temperature silylation was invented. The performance of L-column ODS developed using this method was far superior to that of existing C18 columns, and it became a pioneer of the new-generation end-capping method. L-column2 ODS, surpassing L-column ODS in performance, was developed by upgrading the end-capping method. There is now a demand for RP-HPLC columns capable of both handling various issues of trace analysis due to the popularization of LC/MS(/MS) and providing advanced analytical precision. L-column2 ODS is an ideal column for meeting this demand.

Quality control

Our quality management system is assessed and verified to be in accordance with ISO 9001: 2008 for the design, development, production and supply of columns for gas chromatography and high performance liquid chromatography. We maintain probing inspection systems of raw materials and production processes at each step. All finished products are thoroughly inspected. These steps ensure a tight control of quality. We are continuously refining our operations to supply products for the satisfaction of our customers.
