Column Technology


CTI was founded by chromatography experts to provide superior columns for demanding applications. We are continually developing innovative new products, such as our new biphasic (SCX + C18) and Finnigan ProteomeX-style columns.


Column performance is critical to your research. At CTI, we test every column before it is shipped to you. We are so confident in our columns that we offer a column guarantee – if you are not completely satisfied with the performance of your CTI column, you may return it for a full refund.


We start with silica of the highest possible purity to create phases with exceptional uniformity. Then we pack them into columns at high pressure to ensure stable, reproducible packing and excellent column-to-column reproducibility. All housings, fittings, and materials are chosen to ensure the lowest possible backgrounds during high sensitivity LC/MS/MS analyses.
