Abstract
PURPOSE:To perform the gasification stably and continuously without destroying the specimen component, by performing the gasification such that the flow-out liquid is directly sprayed into an ion source ionization chamber of a mass spectrometer. CONSTITUTION:The flow-out liquid passed through a detector 6 is divided into two with proper ratio by means of a spliter 8, where one is exhausted while the other is supplied to an ion source of a mass spectrometer. An ionization chamber 10 is provided in an ion source block 9 where an electron beam pass port 12 for guiding the shocking electron beam EB produced from a filament 11 and a specimen guide port 13 are provided in the ionization chamber. A guide tube 14 is inserted into the guide port 13 such that the leading edge will reach to the ionization chamber 10, to spray the flow-out liquid from the spliter 8 through the guide tube 14 into the ionization chamber. Since it is ionized instantaneously, the gasification can be continued stably while simultaneously the thermal decomposition of the specimen can be considerably reduced.
