SunShell
SunShell column has not only an inert surface but also high stability due to deactivated silanol groups. SunShell 2.6 μm column can be used on both HPLC and UHPLC because it shows 2 times lower back presure than sub 2 μm column.
SunShell C18 2.6 μm sized 100x4.6mm has the same performance as a totally porous C18 5 μm sized 250x4.6mm, so that the same separation can be achieved by both columns without changing the separation condition consequently analysis time reduces one third.

Product Description
SunShell column has not only an inert surface but also high stability due to deactivated silanol groups. SunShell 2.6 μm column can be used on both HPLC and UHPLC because it shows 2 times lower back presure than sub 2 μm column.
SunShell C18 2.6 μm sized 100x4.6mm has the same performance as a totally porous C18 5 μm sized 250x4.6mm, so that the same separation can be achieved by both columns without changing the separation condition consequently analysis time reduces one third.
Technical specifications
Comparison of theoretical plate and back pressure
Back pressure and theoretical plate were compared for 2 μm and sun 2 μm C18 and 2.6 μm SunShell C18. All columns showed almost the same theoretical plate except for brand A C18 1.9 μm.
However back pressure was not same. Especially Brand C C18 1.7 μm showed the highest back pressure. And SunShell C18 2.6 μm showed the lowest back pressure. On the comparison of theoretical plate per back pressure, SunShell indicated the largest value. This is a big advantage.
SunShell C18 2.6 μm 100 x 4.6 mm showed the same performance as conventional C18 5 μm 250 x 4.6 mm using HPLC.
An analysis time reduces to one third by only changing from conventional C18 column to SunShell C18 column and no changing the other conditions.
SunShell C18 showed 20% higher performance using UHPC than using HPLC.
