The Agilent J&W DB-624 GC column on a 5 inch cage is designed for efficient volatile organic compound (VOC) analysis and residual solvent determination by gas chromatography. With a 20 meter length, 0.18 mm internal diameter, and a 1.00 micron film thickness, this capillary column provides high-resolution separation and sensitivity, making it ideal for pharmaceutical, environmental, and food safety laboratories. Engineered with a proprietary stationary phase of 6 percent cyanopropylphenyl and 94 percent dimethylpolysiloxane, this column delivers excellent peak shape and reproducibility for challenging polar and nonpolar analytes, including alcohols, acetates, and ketones.

This model is fully compatible with a wide range of Agilent GC and GC-MS systems, as well as instruments from other major manufacturers using standard capillary column fittings. It supports methodologies including USP 467 residual solvents and EPA VOC methods, and pairs well with automated headspace samplers or thermal desorption accessories to streamline sample introduction. Laboratories focused on compliance testing or in-depth research benefit from the column’s low bleed and robust temperature stability, ensuring data integrity across repeated analyses. For method development and screening, its selectivity and inertness facilitate reliable quantification of trace-level compounds in complex sample matrices.
