1 Scope
This standard specifies the gas chromatography-mass spectrometry determination method for creosote in cork, the food contact material.
This standard is applicable to the determination of creosote in cork, the food contact material.
2 Principle
Extract the creosote in the specimen by the Soxhlet extractor with absolute ethanol, condense the extracting solution and scale the volume. Filter the extracting solution through the organic microporous filter membrane (0.45μm) and determination it with the gas chromatography-mass spectrometer (GC-MS), carry out the qualitative determination by retention time.
3 Reagents and Materials
Unless otherwise specified, analytically-pure reagents and Class-I water (defined in GB/T 6682) are adopted for the purpose of this method.
