Taking performance to the next stage. With higher sensitivity, longer lifespan, and greater reliability.

Ensure data quality and method performance ■ Secure high reproducibility and reliability even in challenging compound analysis ■ Enable high-sensitivity detection at the picogram level and improve detection limits ■ Enhance operational efficiency by maintaining analytical performance and extending column lifespan The RMX GC column, utilizing TriMax passivation technology, maximizes performance in trace-level analysis, supporting improvements in productivity and profitability. Its exceptional inertness achieves highly symmetrical peak shapes even for challenging active compounds such as acidic and basic compounds, enabling improved linearity of calibration curves and high recovery rates.

basic information

Minimizing the impact of residual active sites, which tend to be problematic in conventional GC columns, achieves high levels of low detection limits, quantitative reliability, and column durability. This design continues to meet stringent data quality requirements for an extended period, even in the current GC analysis environment where the list of analytes is expanding. Long lifespan: Reduced operational burden through extended performance life. Stable calibration curve: Reduced frequency of recalibration, improving data reliability. Quantification in trace regions: Stable response and reproducibility even at low concentration levels. Ultra-inert GC column: Silica surface treatment that minimizes interactions with an extremely inert and clean column inner surface. The TriMax deactivation technology suppresses the effects of residual active sites and surface contamination, forming an extremely inert and contamination-free column inner surface. To accommodate different analytical conditions and maintenance policies, the RMX series offers multiple configuration options. Integral-Guard is a guard column integrated design that minimizes contamination and adsorption on the inlet side, while Integral-Transfer Line is an integrated type for the MS transfer line that prevents sensitivity loss and variability just before the MS. All lineups of the RMX series can be confirmed from related products.

Special public release of past seminar videos that are usually not available! JASIS 2026 'WebExpo'

  • Seminar・Event

This year, we are offering a special public release of previously unpublished seminar videos! We have included a wealth of content that will be useful for analysts, ranging from basic explanations to advanced techniques. You can also download technical materials. 【Videos】 Latest GC columns effective for trace analysis and MS application examples Extreme series: GC WAX column edition, medium polarity GC column edition, PLOT column edition, amine-specific GC column edition, and more. 【Materials】 Development of a simultaneous analysis method for 45 components of ultra-short to long-chain PFAS Newly developed! Evaluation of high-inert GC columns (SVOC analysis) Stability evaluation of PFAS standard solutions Development of an analysis method for 21 PFAS components in milk, and more. -------- 【Highlights of the Real Exhibition】 Booth No. 8B-605 In trace analysis, if you are experiencing "low sensitivity" or "the calibration curve bends on the low concentration side," the cause may be the column. Restek's proposed new technology, "RMX GC Column," suppresses adsorption loss in low concentration areas through its unique inertization treatment. It achieves good peak shape and high reproducibility even for compounds at the picogram level, which are difficult to detect with conventional columns. At the booth, we will provide technical explanations along with actual measurement data, and you can also consult about challenges in the analysis field.
