<P>PROBLEM TO BE SOLVED: To provide a liquid chromatograph mass spectrometer capable of raising ionization efficiency of an ionization interface without lowering the flow rate of a liquid sample to be transmitted from a liquid chromatograph. <P>SOLUTION: The liquid chromatograph mass spectrometer is constituted so that, in a nozzle 221 of an ionization probe 22a for an ESI of an ionization interface, a sample liquid to be supplied to the nozzle 221 is branched to a plurality of flow channels 2211 to be sprayed from the tips of the respective flow channels 2211. By employing such configuration, since the flow rate of the sample liquid decreases in the respective flow channels 2211, the size of droplets to be ejected from each of the flow channels 2211 is reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
