Den lavenergi vand-indkvarteret fraktion (LEWAF) af råolie er en udfordrende system til at analysere, fordi over tid, dette kompleks blanding undergår kemiske omdannelser. Denne protokol illustrerer fremgangsmåder til fremstilling af LEWAF prøven og til at udføre foto-bestråling og kemisk analyse ved fanget ionmobilitetsspektronomi-FT-ICR MS.
