Abstract
A method of analyzing each of a plurality of fluid samples (11-16), comprising, simultaneously spraying a plurality fluid samples (11-16) from electrospray needle array (20) towards mass spectrometer (50); positioning blocking device (40) to block all but one (32-34) of fluid samples (31-34) from reaching mass spectrometer (50); moving electrospray needle array (20) and blocking device (40) relative to one another to permit at least two of the plurality of fluid samples (31, 32) to reach mass spectrometer (50) one at a time; and analyzing the mass spectrum of fluid samples (31, 32, 33, 34) sequentially reaching mass spectrometer (50). A system for analyzing the composition of each of a plurality of fluid samples (31-34), comprising, mass spectrometer (50); multi-head electrospray needle array (20) for spraying fluid samples (31-34) towards mass spectrometer (50); and blocking device (40) positioned between electrospray needle array (20) and mass spectrometer (50), blocking device (40) dimensioned to block all but one (32-34) of fluid sample electrosprays (31-34) from reaching mass spectrometer (50).
