Ensure consistent, predictable liquid chromatography (LC) separations of polar analytes using Thermo Scientific™ Syncronis™ aQ Columns. High surface area silica and dense stationary phase coverage minimize secondary interactions and deliver reproducible high-resolution separations. The polar end-capped C18 phase provides optimal retention of polar analytes and is fully compatible with 100% aqueous mobile phases. Manufactured and rigorously tested in ISO 9000 facilities, these columns are designed to meet a range of analytical needs including fast method development, quantitative analysis, and quality control.

Highly Reproducible Separations
  • Rigorously tested stationary phase bonded to the highest quality silica ensures consistent, predictable LC performance
Excellent Peak Shapes for Enhanced Resolution and Sensitivity
  • Dense surface coverage of silica minimizes secondary interactions and peak tailing
Exceptional Column-to-Column Consistency
  • Manufactured, packed, and tested in ISO-9000-accredited facilities
  • Every column individually tested to meet stringent retention, efficiency, and peak symmetry specifications
  • Enhanced automated packing process
Alternative Selectivity
  • Polar end-capped C18 stationary phase enhances retention of polar analytes
Compatible with Highly Aqueous Mobile Phases
  • Polar end-capping allows use of 100% aqueous mobile phases without loss of performance or stability
Available in Three Particle Sizes
  • 1.7µm for rapid ultrahigh-performance LC (UHPLC) separations, and 3µm and 5µm for more traditional HPLC analysis
