With the Evokeâ„¢ product line, Regis Technologies offers C18 columns for efficient and reproducible separations using reversed-phase chromatography. The material is based on high purity silica, which is endcapped using a unique vapour phase process. The result is a highly inert, hydrophobic surface with a large carbon coverage. This means that higher concentrations of organic solvents can be used, which can be particularly advantageous for electrospray ionisation or preparative applications.
Phase | Particle size | Pore size | pH Range | Max. Temperature | Max. Pressure |
Evokeâ„¢ C18
| 1.8 µm | 100 Å | 2 - 8 | 80 °C | 1034 bar |
3 µm | 100 Å | 2 - 8 | 80 °C | 551 bar | |
5 µm | 100 Å | 2 - 8 | 80 °C | 551 bar | |
10 µm | 100 Å | 2 - 8 | 80 °C | 206 - 413 bar* |
*Depending on the internal diameter of the column: If it is larger than 21.1 mm, only a maximum of 206 bar is applicable.
