Filtration Membranes for mobile phase

Protect your instruments and columns eliminating particulates and gases from mobile phase Nylon and PVDF membrane filters are resistant to a wide range of organic and aqueous solvents. M.E. Cellulose membranes are used for filtration of aqueous mobile phase PTFE membrane filters are ideal for organic solvent

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
