Shodex F7009000 RSpak RP18-415 Polymeric Reversed Phase HPLC Columns, 6µm , 150mm, 4.6mm
Specifications
Reversed Phase Chromatography (RP)
- Separation is based on the partition equilibrium between stationary phase and mobile phase.
- The polarity of the stationary phase is lower than that of the mobile phase.
- Typically the mobile phase contains a mixture of organic solvents (methanol, acetonitrile, or THF) and aqueous solvents (water or buffer).
- Using the lower polarity mobile phase causes a faster elution.
RSpak RP18
- Large pore size is suitable for the analysis of proteins and peptides (biomolecules)
- Corresponds USP LP21
Standard Proteins (3) (RP18-415)
RSpak RP18-415 (a column for reversed phase chromatography) can analyze a variety of proteins with good recovery. This column is suitable for fast analysis at high flow rates since the maximum working pressure is 22Mpa.
