USLC Series (Ultra Selective Liquid Chromatography)

Selectivity is the most influential factor affecting peak separation, or resolution. Restek Ultra Selective Liquid Chromatography (USLC) technology is the directed application of orthogonal selectivity to help the practicing chromatographer develop methods more efficiently and more effectively. The Restek USLC column set offers the widest range of selectivity in the industry using just 4 unique stationary phases—Aqueous C18, IBD, Biphenyl, and PFP Propyl—to simplify phase selection.

Restek USLC columns are available on two silica lines to accommodate any instrument platform or chromatographic application. Pinnacle DB columns (1.9µm) feature base deactivated silica and are recommended for scalable HPLC and UHPLC analyses. Ultra columns (3µm and 5µm) use highest purity silica and are well suited for traditional HPLC analyses.
