GC Columns
Description
Hawach GC columns are high-performance fused silica capillary columns engineered for super inertness, ultra-low bleed, and excellent reproducibility. Available in 11 stationary phases from non-polar (100% dimethyl polysiloxane) to strongly polar (PEG and FFAP), covering USP G2, G3, G7, G16, G27, G35, G42, G43, G46. MS series columns feature ultra-low bleed for GC-MS, ECD, and NPD detectors. Fully compatible with Agilent, Restek, Phenomenex, and other major GC systems.
Why Hawach GC columns rank for analytical laboratories
- Super inert surface deactivation- sharp, symmetrical peaks for active compounds
- Bonded cross-linked technology- low bleed at high temperatures, solvent washable
- Stringent batch testing- consistent inertness and column-to-column reproducibility
- Direct replacements for DB, HP, SPB, Rtx, CP-Sil, ZB, OV series
- MS series optimized for mass spectrometry with ultra-low bleed
Chemical Compatibility & Mobile Phase Guidelines
Compatible with:
- Helium, hydrogen, nitrogen carrier gases
- Standard GC injector and detector conditions
- Solvent rinsing: methanol, dichloromethane, hexane, acetone (for cross-linked phases only)
Not recommended for:
- Non-volatile residues without guard column
- Exceeding maximum temperature limit (phase degradation)
- Aqueous injections without proper phase selection (use FFAP or INOWAX for polar aqueous samples)
