3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 N-alkanes normalalkanes; n-alkanes Straight-chain saturated hydrocarbon structure. 3.2 Accelerated Solvent Extraction acceleratedsolventextraction; ASE At a certain temperature (50 ℃ ~ 200 ℃) and pressure (10.3MPa ~ 20.6MPa) of solid or semi-solid samples with a solvent Extraction method. 3.3 Solid phase extraction and solid-phaseextraction; SPE The use of solid phase extraction column opposite the solid component to be measured suction force is greater than the liquor sample, the sample analytes adsorbed on the solid surface, With the other components of the sample liquor through the column, then an appropriate solvent analytes eluted methods. 3.4 Relative response factor relativeresponsefactor; RRF Standard solution concentration units relative signal intensity ratio of the concentration of the internal standard unit for signal strength.

4 principle of the method

Marine sediment samples n-alkanes (C9 ~ C36), using hexane as the extraction agent with rapid solvent extraction or ultrasonic extraction Extract, extract by solid phase extraction (SPE) and concentrated by gas chromatography - mass spectrometer, using the internal standard method.
