High-Performance Chromatography
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.
Reproducible Batch-to-Batch Performance
Tight particle size distribution and consistent bonding density ensure that your validated method transfers seamlessly from one column lot to the next.
Full Quality Documentation
Every Retrix™ column ships with a lot-specific CoA including theoretical plates, tailing factor, retention factor, USP symmetry, and column back-pressure data.
In-House Technical Support
Our applications scientists assist with method development, troubleshooting, and column selection — available by phone, email or on-site visit.
Competitive Indian-Market Pricing
Premium separation performance without the import premium. Direct distribution model keeps prices sharp and delivery timelines short.
Complete Chromatography Solutions
From reversed-phase HPLC columns to GC capillary columns, vials, liners and filters — Retrix™ covers your entire analytical workflow.
Retrix™ C18
Reversed Phase — High RetentionHigh-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.
Retrix™ C8
Reversed Phase — Mid HydrophobicityLower 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.
Retrix™ GC-1
100% Polydimethylsiloxane — Non-PolarLow-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.
Retrix™ GC-5
5% Diphenyl / 95% PDMS — Mid PolarityMost 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.
