- In most applications in which nonpolar to moderately polar solvents are used; we recommend an intermediate-polarity (IP) deactivated guard column (available in fused silica or MXT).
- For most polar solvents, we generally suggest a polar deactivated guard column.
- For applications that require a highly inert surface to minimize analyte breakdown, such as pesticides analysis, we recommend Rxi guard columns.
- For amines or other basic compounds, we offer base-deactivated guard columns.
- For several of our common stationary phases, we offer Integra-Guard columns: analytical columns with integral guard columns that eliminate the mechanical connection between the guard column and the analytical column.
How do I know which GC guard column would be best for my application?
