Column back pressure halved, achieving high separation! A column that also achieves high durability.
"SunShell" is a core-shell type filling column that achieves efficient silanol group deactivation and high durability by using the improved Sunniest-bonding method for core-shell silica. The core-shell column exhibits equivalent performance (theoretical plates) at half the back pressure of a column with a particle size of 1.8µm. Due to the low back pressure, there are fewer failures in UHPLC even after prolonged use. 【Features】 - Core sizes of 1.6μm, 3.0μm, and 3.4μm with porous layers of 0.5μm, 0.2μm, and 0.6μm - 2.6μm offers the same number of plates as fully porous Sub2μm and 2μm, with the same column pressure as fully porous 3μm - 5μm has the same number of plates as fully porous 3μm and the same column pressure as fully porous 5μm - 3.4μm is a core-shell packing material for rapid protein separation - The reverse phase stationary phases such as C18 and C8 have the same surface treatment as Sunniest 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.
