The reversed-phase HPLC column chemically modified with silanol groups is abbreviated as SAC, which stands for Silanol Activity Control.
The "Sunrise C18-SAC" is an HPLC column that intentionally does not use end-capping, utilizing the properties of residual silanol groups to bond C18. Thanks to silanol activity control technology, it achieves peaks of basic compounds without tailing, even without end-capping. The unique selectivity provided by the regulated silanol groups allows for separations that cannot be achieved with conventional C18 columns.

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.
