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.

TriMax Inactivation Technology Used - RMX GC Column

February 26, 2026 (Thursday) 13:30 - [Webinar] Restek's New RMX Series Debut! High-sensitivity, Long-life, and High-reproducibility GC Columns Utilizing TriMax Inactivation Technology.

  • NEW
  • Seminar・Event

This webinar will focus on Restek's newly announced GC column "RMX Series," explaining the analytical performance achieved through the latest passivation treatment technology and approaches to solving challenges in sample analysis that includes complex matrices. We will introduce the unique features of the new column format specific to the RMX Series and practical points for trace analysis, along with analysis examples using actual samples. We will also concretely present the applicability to routine analysis through actual case studies using the RMX Series. (External speaker: Mr. Eduardo from Weck Laboratories / Japanese dubbing) What you will learn in this webinar: - The features of the advanced passivation treatment technology adopted in the RMX Series GC columns and its analytical advantages. - The concepts for achieving high-sensitivity analysis at trace levels for a wide range of components, including acidic, basic, and neutral compounds. - Common challenges faced in complex sample analysis and solution approaches utilizing the RMX Series. - How selecting the optimal GC column format, including the RMX Series, can lead to improvements in analytical efficiency and lab operations.
