CERI USP and Phase Listing
Customer reference page for CERI L-column USP categories and CERI G-column GC phase matching.
| Category | Description | CERI products |
|---|---|---|
| L1 | Octadecyl silane chemically bonded to porous or non-porous silica or ceramic micro-particles; used for C18 / ODS reversed-phase methods. | L-column3 C18, L-column2 ODS, L-column ODS, L-column ODS-P, L-column ODS-V |
| L7 | Octyl silane chemically bonded to totally porous silica particles; used for C8 reversed-phase separations. | L-column3 C8, L-column2 C8, L-column C8 |
| L11 | Phenyl groups chemically bonded to porous silica particles; used for phenyl selectivity and aromatic interaction methods. | L-column2 C6-Phenyl |
| GC phases | USP GC method column selection should be matched by stationary phase chemistry, polarity, dimensions, film thickness and method requirement. | CERI G-100, G-205, G-230, G-250, G-300, G-450, G-950 |
Method matching note
Always confirm the exact validated method requirement, stationary phase, particle size, column dimensions and catalog number before substitution.
