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.
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.

CERI 622078 L-column ODS-V C18 Octadecyl HPLC Column, 4.6mm x 150mm, 5μm Particle Size
Physical property information
Particle size 3 μm, 5 μm Pore size 12 nm Specific surface area 340 m 2 / g Carbon content 17% Modifying group C18 (Octadecyl) End capping method High temperature gas phase endcapping USP category L1 Used pH range pH 2 to 9 L-column ODS appeared in 1990 as a column eliminating secondary interaction by residual silanol groups by high-temperature gas-phase end capping method. At that time the performance outstanding of the commercially available ODS column was positioned as a pioneer column. It is a column that you can use with confidence by stable supply for many years.
L-column ODS-V (with particle size 5 μm only) with certificate (Certificate of analysis )
L-column ODS-V has attached "Certificate of analysis" to L-column ODS . "Certificate of analysis" proves that the physical property values and separation behavior of the lot are within the standard. We support analytical method validation.
