A highly sensitive and selective on-line two-dimensional reversed-phase liquid chromatography/electrospray ionization-tandem mass spectrometry (2D-LC-ESI/MS/MS) method was developed and validated to determine rifaximin in rat serum by direct injection. The 2D-LC-ESI/MS/MS system consisted of a restricted access media column for trapping
