This study focused on using liquid Chromatography Tandem Mass Spectrometry to detect N-Nitrosodimethylamine (NDMA) at trace concentrations in water. The water sample was preconcentrated by solid-phase extraction method. To find an elution which can obtain higher recovery, three reagents with different organic solvents were examined. After comparing the recoveries and the standard deviation of the elution, finally the dichloromethane was determined as the elution of the experiment. Then the concentrated sample was analyzed by a method combining SPE pretreatment and LC separation with tandem mass spectrometry using multiple reaction monitoring (MRM).
