The OV-PLOT and U-PLOT Gas Chromatography Capillary Columns are high-performance, polar and specialized stationary phase columns designed to provide exceptional separation of permanent gases, light hydrocarbons, and volatile organic compounds. Featuring robust fused silica construction and proprietary bonded phases, these columns offer excellent thermal stability, low bleed, and long operational life, ensuring consistent and reproducible results even under demanding analytical conditions. The OV-PLOT column, with its optimized polar stationary phase, is ideal for the separation of permanent gases, light hydrocarbons, and small polar molecules, providing sharp peak shapes and superior resolution for routine and research applications. Meanwhile, the U-PLOT column is designed specifically for high-efficiency separation of hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, and other permanent gases, making it indispensable for environmental, petrochemical, and industrial gas analyses. Both column types are compatible with most GC and GC–MS systems, offering flexible length, internal diameter, and film thickness options to meet diverse analytical requirements. These columns deliver reliable performance, high sensitivity, and precise quantitation, enabling laboratories to achieve accurate, high-resolution separations for a wide range of gaseous and volatile compounds.
