Suitable for the analysis of small molecules.
Step 2 of the European Standard (EN 15662) Supra-d QuEChERS Dispersive SPE method to perform multiple pesticide residue analysis.
General purpose bare silica columns for normal phase and HILIC applications.
Suitable for the analysis of small molecules.
Silica based support for larger anionic compounds.
Reduced activity C18 phase recommended for the fast, reversed-phase separation of basic compounds/pharmaceuticals.
Highly retentive and selective for protonated basic analytes and molecules containing aromatic moities.
Polyfunctional ODS phase to provide slight differences in selectivity.
Step 2 of the American AOAC Standard (AOAC 2007.01) Supra-d QuEChERS Dispersive SPE method to perform multiple pesticide residue analysis.
Sterically protected ligand (isobutyl-side chains), results in an extra stable bonded phase at low pH where most peptide separations are performed.
Reduced activity C8 phase recommended for the fast, reversed-phase separation of increasingly basic compounds.
