A sensitive liquid chromatography tandem mass spectrometry (LC-MS/MS) method for the determination of adenosine concentrations in mouse brain microdialysis samples was developed. High method sensitivity (LLOQ of 1.25 fmol) was achieved by on-line switching column. A C18 was employed as enrichment column and a cyano based (CN-SB) as analytical column. The method was fully validated for its sensitivity, selectivity, matrix effect and stability. It was successfully applied to measure quantitatively adenosine in brain of freely moving mice after different stimuli.
