FAQ
What Is The pH Range For XTerra Shield Rp8 Columns? XTerra columns are known for a widened usable pH range when compared with silica-based columns. RP columns feature a pH range of 2-12.
While lifetime is greater with these columns than others, it is still finite and can vary based on the buffers used, the concentration of buffers, and the temperatures at which they are used. See the manual you receive for recommended buffers when developing methods.
Note that high pH use of Phosphate is not recommended, even though it can give longer lifetimes than silica-based columns.
