Abstract: An electrospray ion source is fitted with plural spray nozzles. A nebulization gas is supplied to the nozzles. The supply of the nebulization gas to at least a selected one of the spray nozzles is cut off for a given time. The application of the high voltage to the spray nozzle, for which the supply of the nebulization gas is cut off, is synchronously ceased.
