GC Columns

GC Columns Superior Gas Chromatography Columns for Life Sciences, Environmental Testing & Chemical Analysis. 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) Choose the Right GC Column in 30 Seconds If you need… Choose… Non-polar, boiling point separation H1-1 / H1-1MS (100% dimethyl) General-purpose semi-volatiles, drugs, pesticides H1-5 / H1-5MS (5% phenyl) VOCs, residual solvents, EPA methods H1-624 (6% cyanopropyl) Medium polarity, pharmaceuticals, steroids H1-17 / H1-17MS (50% phenyl) FAMEs, cis-trans isomers H2-225 (50% cyanopropyl) Polar compounds (alcohols, solvents) H1-INOWAX (PEG) Volatile fatty acids, phenols H1-FFAP (acid-modified PEG) Direct Replacement Cross Reference Hawach Equivalent H1-5MS DB-5MS / HP-5MS / Rtx-5MS H1-624 DB-624 / HP-624 H1-INOWAX DB-WAX / HP-INNOWax H1-FFAP DB-FFAP / Stabilwax-DA Core Specifications Parameter Value Column type Fused silica capillary Bonding Chemically bonded, cross-linked (solvent rinsable) Surface deactivation Advanced inertness process Lengths 15, 30, 60 m (custom available) IDs 0.20, 0.25, 0.32, 0.53 mm Film thickness 0.10-1.50 μm Temp stability Up to 350°C (phase dependent) MS bleed <5 pA at 325°C Reproducibility Retention time RSD ≤1% Application Guide by Phase Application Recommended Phase Boiling point distribution, hydrocarbons H1-1 Semi-volatile organics (EPA 8270) H1-5 Volatile organic compounds (VOCs) H1-624 Residual solvents in pharmaceuticals (USP <467>) H1-1301 or H1-624 Pesticide residues H1-5 or H1-1701 Fatty acid methyl esters (FAMEs) H2-225 Alcoholic beverages H1-INOWAX Free fatty acids, phenols H1-FFAP Drug screening H1-35 or H1-5 Steroid hormones H1-17 Key Performance Advantages Super inertness -Sharp, symmetrical peaks for active compounds (amines, acids, alcohols) Ultra-low bleed (MS series) -Higher S/N for GC-MS, ECD, NPD Solvent washable -Cross-linked phases extend column life Consistent reproducibility -Each column tested with mixed standard;

FAQ Difference between H1-1 and H1-1MS? H1-1MS has ultra-low bleed, designed for GC-MS, ECD, NPD. Which column for residual solvents (USP <467>)? H1-624 or H1-1301 – both meet USP G43. Which column for FAMEs? H2-225 – specific for cis-trans isomer separation. Compatible with Agilent GC systems? Yes. Standard dimensions fit Agilent, Shimadzu, Thermo, PerkinElmer. Do you offer custom dimensions? Yes – OEM custom lengths, IDs, film thicknesses available. Are MS columns suitable for ECD? Yes – ultra-low bleed reduces detector contamination.
