FAQ
What pH Range And Temperatures Are Recommended For Spherisorb ODS2 Columns? The Spherisorb ODS2 Columns operate best in pH range 2 to 8. Column lifetimes will vary and also depend on the operating temperature, and the type and concentration of buffer used. For instance, you can expect a shortened column lifetime with the use of phosphate buffer at pH 8 in combination with raised temperature.

The recommended operating temperatures for Spherisorb ODS2 Columns are between 20 to 45 °C. This ensures enhanced selectivity, lower solvent viscosity, and increased mass transfer rates. It is noteworthy that any temperature above ambient may reduce the lifetime of the column. To ensure a long column lifetime, adhere to recommended pH range, temperature, and buffer conditions.
