Rapid confirmation and quantitation of drugs-of-abuse in oral fluid using a low cost, small footprint mass spectrometer

Recent developments in the miniaturisation of mass spectrometry have led to a new generation of low-cost instruments which are making MS a more accessible technology in all areas of analytical science. While the utility of these instruments for qualitative analysis has been demonstrated, their usefulness for quantitative analysis – particularly in complex matrices – has not been proven. Here we describe the development of a rapid LC-MS method...
