| Definition | ALS S-SPIHSP01 - ALS analysmetod för bestämning av volatila alifatiska och aromatiska kolväten i i jord, slam och sediment. Analys utförs med Headspace-GC-MS metod enligt SPIMFABs kvalitetsmanual. "The weight of the sample is extracted with methanol in a closed vial after the adding of the surrogate standard and internal standards. An aliquot portion of the methanol extract is dosed into a HS vial, in which a defined volume of reagent water (15 ml) is presented and the vial is closed with a lid. The vial is incubated at a defined temperature and time. Vapors of volatile organic compounds are injected into a chromatographic column after the liquid-vapor interphase balance has been established, where they are separated. The separated compounds are identified by mass detector after recording spectra in SIM mode in the range of 35-200 amu. Quantification is performed by comparing the responses of identified substances in the sample and external standards followed by corrections to the response of internal standards." |
