Preferred label	ALS_S_VOCGMS04
Definition	S-VOCGMS04 - ALS analysmetod för bestämning av flyktiga organiska föreningar i i jord, slam och sediment: Analys av: 1) Naftalen. 2) +Halogenerade volatila organiska föreningar. 3) Ickehalogenerade volatila organiska föreningar. Metod baserad på US EPA 8260, US EPA 5021A, US EPA 5021, US EPA 8015, CSN EN ISO 22155, CSN EN ISO 15009, CSN EN ISO 16558-1, MADEP 2004, rev. 1.1. Mätningen utförs med GC/MS och GC/FID. "Solid sample is extracted into methanol in a closed vial. An aliquote part of the methanol extract is added to a headspace vial with a pre-defined amount of reagent water. The vial is incubated for the defined time and temperature. After establishing the liquid-gas equilibrium, the vapours of volatile organic compounds are injected to chromatographic column where they are separated. Separated compounds are identified in mass spectrometer and quantified in detector, based on the response magnitude of the amount of substance."
