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.
Claims5
An electrospray ion source having plural spray nozzles which can be supplied with a nebulization gas and to which a high voltage can be applied, said spray nozzles being used substantially simultaneously,
- wherein the supply of said nebulization gas to at least a selected one of said spray nozzles is cut off for a given time.
An electrospray ion source having plural spray nozzles to which a high voltage can be applied, said spray nozzles being used substantially simultaneously,
- wherein the application of said high voltage to at least a selected one of said spray nozzles is ceased for a given time.
An electrospray ion source having plural spray nozzles which can be supplied with a nebulization gas and to which a high voltage can be applied, said spray nozzles being used substantially simultaneously,
- wherein an operation for cutting off the supply of said nebulization gas to at least a selected one of said spray nozzles for a given time and an operation for ceasing the application of said high voltage to at least a selected one of said spray nozzles for a certain time are carried out synchronously for the same selected spray nozzle.
