Preferred label	ALS_S_SPIGMS03
Definition	S-SPIGMS03 - ALS analysmetod för bestämning i jord, slam och sediment av: 1) Alifatfraktioner och aromatfraktioner. 2) Polycykliska aromatiska kolväten, PAH (16 föreningar enligt EPA). 4) Summa metylpyrener/metylfluorantener och summa metylkrysener/metylbens(a)antracener. GC-MS metod enligt SPIMFAB:s kvalitetsmanual. "After addition of extraction standard, the sample is extracted with a pentane-methanol mixture with the final extract in pentane. After shaking with acidified water, the organic phase is isolated and analyzed by capillary gas chromatography with mass detection, when spectra are recorded in SIM or SIM/SCAN mode. Quantification is performed by the external standard method followed by corrections to the recovery of the extraction standard."
