Restek Company Overview

Non-specific adsorption (NSA) and non-specific binding (NSB) to metal surfaces are major causes of peak disappearance, sensitivity reduction, and poor reproducibility in the LC MS/MS analysis of pesticides, mycotoxins, and acidic polar compounds. Traditionally, the only way to address these issues was through complex conditioning or "band-aid" solutions using mobile phase additives. In this webinar, we will provide a detailed explanation of how Restek's Inert LC column technology fundamentally resolves these challenges, supported by real data. We will showcase how the Inert series, including Raptor ARC 18 and Raptor Biphenyl, improves peak shape, peak area, and LOD for metal-sensitive compounds, with specific examples from pesticide analysis, mycotoxins, PFAS, and phthalate ester analysis. This content is recommended for anyone involved in multi-component analysis using GC/MS, whether for target or non-target analysis, and for those who are just starting. We will explain it in an easy-to-understand manner for GC/MS beginners. https://attendee.gotowebinar.com/register/1160201828261205080

This year, we are offering a special public release of previously unpublished seminar videos!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.
