Further evolution of surface treatment! HPLC columns that achieve astonishing alkali resistance.
"SunArmor" is an HPLC column that achieves remarkable alkali resistance while being silica gel particles, thanks to the newly developed silylation agent and TMS for final end-capping, in addition to the conventional Sunniest end-capping. The usable pH range of the mobile phase with the C18 stationary phase is from 2 to 12, providing durability equivalent to hybrid silica. A high-durability NH2 column has been added. 【Features】 ○ Superior alkali resistance compared to other hybrid C18 columns ○ Not affected by residual silanol groups ○ Exhibits good peak shapes for acidic, basic, and metal-coordinating compounds For more details, please contact us or download the catalog.

Company information
Chromatic Technologies, a company that manufactures and sells UHPLC/HPLC columns, will celebrate its 20th anniversary in 2025. The surface porous core-shell columns have been manufactured and sold in Japan since 2011, making it one of the earliest producers, and currently supply core-shell columns under private labels to 12 HPLC column manufacturers worldwide. The company is engaged in research and development of UHPLC/HPLC columns and presents academic papers at domestic and international conferences related to HPLC (such as the Japan Society for Analytical Chemistry, the Chromatography Science Conference, the Pharmaceutical Society of Japan, HPLC, ISC, Pittcon, etc.). At HPLC2022 held in San Diego (CA, USA) in 2022, they made a poster presentation and exhibited, and included photos from the exhibition in their corporate PR materials.
