SunShell 2-Ethylpyridine
SunShell SFC Columns
SunShell 2-Ethylpyridine column is manufactured specifically for SFC applications using innovative core shell particle technology that provides significantly increased column efficiency and chromatographic resolution without the high back pressure seen in sub 2-µm columns.

Features of SunShell
- Provides the same high efficiency and high speed as sub-2 µm
- Less than half the backpressure of sub-2 µm
- Up to 100 times higher loading capacity compared to other core shell materials
- Improved pH stability from 1.0 to 10 (C18)
Comparison of SunShell 2-EP and sub-2µm particle 2-EP
Using a mixture of 17 small drug-like compounds under similar SFC conditions, SunShell 2-Ethylpridine column outperformed sub-2µm particle 2-ethylpyridine phases for overall selectivity.
Figure 1:
Chromatogram of the separation for the 17-component mix using the Sun Shell 2-EP column. A methanol gradient of < 2 minutes was used on the Agilent 1260 Infinity SFC system. SFC conditions: flow rate: 4.0mL/min; outlet pressure 160 bar; column temperature 55°C. Gradient program: 5.0-7.5% in 0.20 min, then 7.5-20% in 1.3 min and held at 20% for 0.2 min.
Figure 2:
Chromatogram of the separation for the 17-component mix using the Acquity UPC2 Viridis 2-EP column. 16 of the 17 components were resolved. A methanol gradient of < 2 minutes was used on the Agilent 1260 Infinity SFC system. SFC conditions: flow rate 3.5 mL/min; outlet pressure 160 bar; and column temperature 70°C. Gradient program: 5.0-12.5% in 1.0 min, 12.5% for 0.25 min, then 12.5-20% in 0.75 min.
