From reversed-phase HPLC columns to GC capillary columns, vials, liners, and filters — explore the full Retrix™ range.
Retrix™ is Zynra's proprietary brand of analytical chromatography media. Every column is manufactured to exacting tolerances, shipped with a Certificate of Analysis and lot-specific test chromatogram, and backed by our in-house applications team.
Whether you are running ICH Q3C residual solvent methods on a GC or performing impurity profiling of a pharmaceutical API by UHPLC, Retrix™ gives you the selectivity, efficiency, and reproducibility that your regulatory submissions demand.
From reversed-phase HPLC columns to GC capillary columns, vials, liners and filters — Retrix™ covers your entire analytical workflow.
High-density octadecyl bonding on ultra-pure silica. Outstanding stability across pH 2–10. The workhorse column for pharmaceutical impurity profiling, API assay, and USP/BP method execution.
Lower hydrophobicity than C18, ideal for polar compounds and basic drugs. Excellent peak shape for amines and base-labile analytes at alkaline pH without ion-pairing reagents.
Pi–pi interaction with aromatic and conjugated analytes gives unique selectivity complementary to C18. Use as orthogonal confirmation or for analytes that co-elute on alkyl phases.
Retains polar, hydrophilic analytes that pass through reversed-phase columns. Ideal for sugars, nucleotides, amino acids, polar metabolites, and highly polar APIs. MS-compatible mobile phases.
Low-bleed, non-polar stationary phase equivalent to DB-1/HP-1. General purpose for solvents, aliphatic hydrocarbons, and non-polar compounds. Excellent thermal stability up to 350°C.
Most widely used USP GC phase (G27). Compliant with ICH Q3C residual solvent methods. Excellent peak shape across a broad range of analyte polarities. Low column bleed for MS detection.
High-polarity PEG stationary phase for excellent resolution of alcohols, esters, ethers, and aroma compounds. Essential for food, flavor, and fragrance analysis.
Porous layer open tubular column for light gases, permanent gases, and VOC analysis. Available in Al₂O₃/KCl and molecular sieve variants for permanent gas separations.
