C18, C8 & C4 (100, 200 & 300 Angstrom) for peptide, protein and biomolecule analysis.
Unique Base Deactivated columns. Exceptional separations for amines and polar molecules.
300Å or 200Å for Peptides and Proteins.
Available in stainless steel or PEEK. Designed to use the Direct Connect Guard System.
Thomson reverse phase columns are designed for the chromatography of peptides and proteins. They are characterized by high resolution, efficiency and peak symmetry.
Available in C4, C8 or C18 phases, 100Å, 200Å, or 300Å pore sizes and 3µm or 5µm particle sizes.
Take advantage of the better resolution, for small molecules, afforded by the high surface area, 100Å packing, or separate larger molecules on the 300Å packing. Their identical selectivity allows you to maintain the same elution order from one product to the other.
Chromatographing small proteins or peptides on a 300Å packing is conventional wisdom. But in many cases the higher surface area support would be the better choice. Now we offer an intermediate surface area with our 200Å materials.
These columns, perfect for LC/MS, provide excellent resolution without TFA or other modifiers. Or chose a modifier other than TFA, to enhance selectivity for the compounds of interest.
