New stationary phase "Biphenyl"
SunShell Biphenyl, Prominert Biphenyl, Sunniest Biphenyl
Separation completely different from alkyl group-type stationary phases such as C18 is achieved due to the interactions of π electrons (π-π and CH-π interactions).
"Biphenyl" has two benzene rings twisted at approximately 45 degrees, and the biphenyl group exhibits different separation behavior from a single phenyl group as a core-shell. Even when using an aqueous mobile phase that does not contain organic solvents, there is no change in retention. The retention of polar compounds like caffeine increases significantly. Other companies' Biphenyl products mostly use monofunctional silylation reagents, while our "Biphenyl" uses highly acid-resistant trifunctional silylation reagents.

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.
