3 Days to Go! Implementation of the New National Standard for Methanol—Version 5.1 | Corei Chromatography Provides a One-Stop Solution for Detecting 19 Impurities

Effective May 1, 2026, GB/T 46434-2025, “Determination of Methanol Purity and Trace Organic Impurities—Gas Chromatographic Method,” will be officially implemented. As the nationally unified official standard for industrial methanol testing, it completely replaces traditional, less rigorous testing methods and sets more precise and stringent requirements for the determination of methanol purity (≥99.0%) and 19 specific organic impurities, directly impacting the compliance and testing efficiency of chemical enterprises and laboratories.
