Count on CTI for innovation! 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.

Count on CTI for quality! 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.

Count on CTI for performance! 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.

PepSil™: Ion exchange and reversed phase support peptide separation with unprecedented performance. PepSil C18 columns exhibit superb reproducibility and resolution, and extremely low sample carry-over. Our 75, 150, 320 μm, 1.0mm and 2.1mm formats are packed using a proprietary method that ensures uniform packing and excellent sensitivity. Use PepSil columns to identify as many peptides as possible in your sample.

AccuSil™: Reversed phase supports small molecule quantitative assays with exceptional performance. Available in 1 and 2.1 mm formats, AccuSil columns deliver excellent separations, very low carry-over, and robust performance for demanding assays.
