Hypersil GOLD columns – the right place to start

Significance of the Topic

Analytical separations using high-performance liquid chromatography are fundamental to pharmaceutical development, quality control, environmental testing and food analysis. The choice of column chemistry directly impacts peak shape, retention behavior and method robustness, making an informed selection essential for reliable results.

Objectives and Study Overview

This document presents the Thermo Scientific Hypersil GOLD family of HPLC and UHPLC columns. It describes the baseline C18 phase and its C8, aQ and HILIC variants, outlining their targeted applications and performance strengths in method development.

Methodology and Instrumentation

Performance data were generated on standard HPLC and UHPLC systems using fully porous silica columns with particle sizes from 1.9 µm to 5 µm and internal diameters from 2.1 mm to 4.6 mm. Guard cartridges compatible with Thermo’s UNIGUARD holders protect analytical columns from matrix contaminants and extend their usable lifetime.

Main Results and Discussion

• Hypersil GOLD C18 delivers symmetric peaks across acidic, neutral and basic analytes, serving as a versatile starting phase.
• GOLD C8 reduces hydrophobic retention when analytes elute too slowly, maintaining similar selectivity with shorter runtimes.
• GOLD aQ minimizes peak tailing for polar or basic compounds and supports 100 % aqueous mobile phases for enhanced reproducibility of early eluting species.
• HILIC phases improve retention of highly polar and hydrophilic compounds that are challenging under reversed-phase conditions.

Benefits and Practical Applications

• Consistent peak shape for a wide range of chemical classes
• Adjustable retention via C8 and aQ variants to optimize run times
• 100 % water compatibility for robust separation of polar analytes
• Seamless method transfer between HPLC and UHPLC platforms

These features reduce development time and enhance reproducibility in regulated laboratories and research settings.

Future Trends and Potential Applications

The growing adoption of ultra-high-pressure chromatography will drive demand for sub-2 µm particles to achieve higher resolution in shorter analyses. Advances in metabolomics, proteomics and clinical diagnostics will benefit from customized stationary phases for challenging analytes. Integration with automated sample preparation and real-time data analysis will further streamline workflows.

Conclusion

Thermo Scientific Hypersil GOLD columns offer a reliable and flexible solution for chromatographic method development. Their broad applicability, consistent performance and compatibility with various mobile phase conditions make them an ideal choice for both routine analyses and advanced research applications.
