Kore KRGC-MEOH 203 Gas Chromatograph for Methanol Purity and Impurity Analysis

Kore KRGC-MEOH 203 Gas Chromatograph for Methanol Purity and Impurity Analysis

The gas chromatograph for methanol purity and impurity analysis is a dedicated GC system designed for coal‑chemical, fine‑chemical, and solvent‑production enterprises. It is primarily used for the qualitative and quantitative analysis of key components in industrial methanol, purified methanol, and chemical solvents, including methanol content, ethanol, acetone, aldehydes and ketones, and organic impurities.

Methanol is an important basic chemical feedstock, widely used in coal‑chemicals, fine chemicals, new materials, fuels, and downstream synthesis applications. As quality‑control requirements for methanol continue to tighten, the accurate identification and quantitative analysis of trace organic impurities—beyond the main methanol content—are receiving increasing attention from manufacturers, quality‑inspection agencies, and downstream users.

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

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.
