Rtx-624
Restek Rtx-624 GC Columns
Restek Rtx-624 GC columns feature a 6% cyanopropylphenyl, 94% dimethylpolysiloxane stationary phase
specifically engineered for the separation of volatile organic compounds (VOCs) in environmental,
pharmaceutical, flavor/fragrance, and industrial applications. As one of the industry’s most widely used
624-type phases, Rtx-624 provides optimized mid-polarity selectivity and exceptional chromatographic
performance for purge-and-trap, headspace, and direct-injection workflows.
The balanced polarity of Rtx-624 supports efficient separation of a broad range of volatile analytes— including alcohols, solvents, esters, ketones, halocarbons, and small oxygenated species—making it a cornerstone for EPA VOC analysis (e.g., 524.2, 624, 8260) and residual solvent testing. With consistent retention behavior, excellent peak shapes, and reliable resolution of critical pairs, Rtx-624 excels in complex multicomponent mixtures.
Designed for high thermal stability and low bleed, Rtx-624 provides robust performance in GC and GC-MS, supporting sensitive quantitation and long column lifetimes. Its strong inertness ensures minimal adsorption or distortion of reactive or polar compounds, improving accuracy across regulatory and high-throughput methods.
As an authorized Restek distributor, Chrom Tech supplies Rtx-624 columns in a wide range of dimensions to meet the demands of environmental water testing, pharmaceutical quality control, industrial VOC monitoring, and general-purpose volatile analysis workflows.
