Restek Rtx-50 GC Columns
Restek Rtx-50 GC columns feature a 50% phenyl, 50% dimethylpolysiloxane stationary phase that provides
mid-polarity selectivity ideal for separating compounds influenced by both aromatic interactions and
dipole-related retention. This balanced phase chemistry makes Rtx-50 highly effective for analyzing a wide
range of semi-volatile and thermally stable compounds across environmental, pharmaceutical, petrochemical,
flavor and fragrance, and specialty chemical applications.
The increased phenyl content enhances retention of aromatic, halogenated, and polarizable compounds, enabling improved resolution of complex mixtures where structural similarity or co-elution challenges conventional phases. Meanwhile, the column maintains strong thermal stability and predictable retention, supporting both routine QA/QC workflows and advanced analytical method development.
Rtx-50 columns offer low bleed, clean baselines, and excellent peak symmetry, producing reliable results in GC and GC-MS applications—especially where selectivity beyond traditional low-polarity phases (such as Rtx-1 or Rtx-5) is required. Their proven reproducibility ensures strong method transferability and long-term consistency in regulated and high-throughput laboratories.
Chrom Tech, as an authorized Restek distributor, supplies Rtx-50 columns in a variety of dimensions to match specific analytical needs, from aromatic speciation to impurity profiling and detailed semi-volatiles analysis.
