  • Description

    LC/MS/MS is a powerful and widely used tool in qualitative and quantitative residue and contaminant analysis. The mixture is separated with HPLC prefer ably using a reversed-phase column. The analyses can be ionized with a suitable ion source by various methods, followed by partial fragmentation. After acceleration, they are deflected by a magnetic field which resolves them according to their mass.
