ActiveDetermination of trace trimethylamine in methanol for industrial use—Gas chromatography-mass spectrometry
工业用甲醇中痕量三甲胺含量的测定 气相色谱质谱联用法
Application Summary AI generated
This standard specifies a gas chromatography-mass spectrometry method for determining trace amounts of trimethylamine in methanol intended for industrial use. It is applied in quality control and testing laboratories within the chemical industry to ensure methanol purity meets specifications for downstream applications, such as in the production of formaldehyde, acetic acid, or as a solvent. The method is particularly relevant for detecting low-level amine contaminants that could affect catalytic processes or product quality in sensitive chemical manufacturing contexts.
