High Speed Separations Smaller reduced plate heights lead to high efficiencies; narrower and taller peaks, for improved resolution and lower detection limits (LODs and LOQs) Flat van Deemter plot and higher linear velocity optimum allow higher flow rates with minimal column efficiency loss High Resolution Separations High efficiency with longer geometries (100, 150, 250 mm) provides greater resolving power for challenging applications Lower back pressure permits columns to be used in series for the most demanding UHPLC and HPLC separations Excellent Ruggedness and Reproducibility Less plugging, longer usable column lifetime and greater uptime due to larger porosity frits (vs. sub-2 µm totally porous (non-core) columns) 2 µm frits for HALO 2.7 and HALO 5 1 µm frits for HALO 2 vs. 0.2–0.5 µm frits for sub-2 µm non-core columns Excellent column-to-column and lot-to-lot reproducibility
