HALO Fused-Core Performance

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
