The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications.
Restek chemists developed the Ultra Carbamate column specifically for carbamates analysis. The unique packing separates 10 target carbamates in just 5 minutes with an 8 minute total cycle time. The column is compatible with fluorescence or LC-MS detection.* An Ultra Carbamate column can process as many as eight samples per hour, versus less than two samples per hour on a general-purpose C18 column. In addition to increased sample throughput, this much faster analysis will significantly reduce solvent usage—and the costs of disposing of solvent waste.

*For post-column derivatization/fluorescence detection applications using a 4.6 mm ID column, the total system dead volume, including the post-column reactor, must be less than 650 μL. For standard post-column reactor systems, we recommend a 250 mm x 4.6 mm, 5 μm column. Contact Restek Technical Service or your local Restek representative for more information.
