    Method development for the analysis of mono-carbonyl compounds in e-vapor products by LC-MS

    ZHU J.; HEREDIA A.; TWEEDY J.; TAYYARAH R.
    ITG Brands and Fontem USA, Greensboro, NC, U.S.A.
    At the 73rd Tobacco Science Research Conference (TSRC), we presented a novel method for quantitation by LC-MS of mono-carbonyl compounds in e-vapor product aerosol samples. The method is simple and robust with good recoveries. We have since extended...
