CERI L-column RP-HPLC Columns

Chemicals Evaluation and Research Institute, Japan (CERI) engages in a wide scope of activities related to chemicals, including testing, analysis, evaluations, and research and development. Our ultimate objective is to further the sound development of industry and enhance people’s lifestyles by upgrading the quality of chemicals and assuring their safety while at the same time emphasizing environmental preservation and the protection of health. As an independent, unbiased organization that is committed to keep chemicals and the environment in balance, CERI plays a supporting role in the research and development projects of clients utilizing its services. Working in state-of-the-art facilities, our highly qualified professionals conduct tests, analysis, research, and studies in the field of chemicals.

CERI developed a high temperature vapor-phase end-capping technique in 1990 which was patented in Japan, the United States and Europe (JP 2611545, USP 5,134,110 and EP 0 443 860 B1, respectively). This method dramatically improved the reaction efficiency of end-capping so that very few residual silanols and metallic impurities remain to effect the separation. The L-column ODS demonstrates near ideal ODS performance and was placed as a pioneer among commercial HPLC columns.

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.
