T/ZJSES 6-2024 Sludge determination of petroleum hydrocarbons (C10-C40) by gas chromatography
Basic Information
Scope
Main technical content: (1) Determination principle: The petroleum hydrocarbons (C10-C40) in sludge are extracted, purified, concentrated, and quantified using a gas chromatograph equipped with a hydrogen flame ionization detector (FID). The components are identified based on their retention time and quantified using an external standard method. (2) Instrumentation and equipment used: Gas chromatograph, pressurized fluid extraction device, vacuum freeze dryer, Soxhlet extractor, nitrogen blowing concentrator, rotary evaporator, etc. (3) Main technical content: (1) Requirements for sludge sample collection and storage; (2) Methods for sludge sample preparation and pretreatment; (3) Determination method for the content of petroleum hydrocarbons (C10-C40) in sludge; (4) Quality control requirements
