Advanced GC columns for high-performance analysis

Restek introduces RMX GC columns powered by TriMax deactivation

Restek has expanded its gas chromatography portfolio with the launch of RMX GC columns, engineered to deliver exceptional inertness and reliable trace-level detection for challenging analytical applications. Featuring proprietary TriMax deactivation technology, the new columns are designed to support confident reporting of active and difficult analytes across a broad range of compound classes, including acids, bases, and alcohols.

At the core of RMX performance is TriMax technology, which produces an ultra-clean, highly inert column surface. By minimising residual active sites commonly associated with conventional deactivation approaches, TriMax enables sharper peak shapes, improved reproducibility, and enhanced sensitivity at very low detection limits. The robust surface chemistry also helps maintain performance after repeated thermal cycling and exposure to complex sample matrices, extending column lifetime in demanding workflows.

According to Restek, the development of TriMax involved purpose-designed reagents and tightly controlled processing to form a dense, three-dimensional deactivation network. This approach delivers consistent inertness and durability, even under conditions that typically degrade column performance.

RMX GC columns are designed to help laboratories respond to evolving analytical pressures, including lower detection requirements, expanded analyte lists, and changing solvent and regulatory landscapes. Their high sensitivity and stability support long-term data quality while enabling reduced sample preparation volumes and more efficient workflows.

With a combination of broad analyte compatibility, dependable performance, and long service life, RMX columns provide laboratories with a practical solution for maximising productivity while maintaining analytical confidence.
