Abstract

A mass spectrometry-based method for analyzing an acidic organic target compound includes directing a charged solvent (44) toward a pre-acidified sample (12) comprising the target compound, to thereby ionize the pre-acidified sample (12). The method further includes directing the ionized pre-acidified sample (54) to a mass spectrometer (18), the mass spectrometer (18) being configured to identify and quantify the target compound.
