Restek USLC columns

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 a wide range of selectivity using four stationary phases - Aqueous C18, IBD, Biphenyl and PFP Propyl - to simplify phase selection and column choice for fast, effective method development.

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

The columns offer good control to better resolve closely eluting peaks, and they fit on any HPLC or UHPLC instrumentation. Column screening is maximised by ensuring orthogonality between analytical runs.
