GC Column

GC Capillary Columns by CHROMOSEP are engineered for exceptional resolution, sensitivity, and stability in gas chromatographic analyses. Crafted from high-purity fused silica and protected with a durable polyimide coating, these columns combine superior inertness with mechanical strength for consistent performance across a wide range of analytical applications.With inner diameters from 0.1 mm to 0.53 mm and lengths up to 100 meters, CHROMOSEP capillary columns deliver ultra-high separation efficiency and reproducible peak shapes, ensuring accurate identification and quantification of complex mixtures. The precisely bonded stationary phases—available in WCOT, SCOT, and PLOT configurations—enable optimized selectivity for diverse analytes, from volatile organics to complex hydrocarbons. The Wall-Coated Open Tubular (WCOT) design features a chemically bonded stationary phase for outstanding thermal and chemical stability, while Support-Coated Open Tubular (SCOT) and Porous-Layer Open Tubular (PLOT) variants offer enhanced performance for specific gas and volatile compound separations. Each column is rigorously tested to guarantee low bleed, high signal-to-noise ratios, and long operational life, even under demanding analytical conditions.
