摘要:
A positive ion of an isomer is generated in an ion source and introduced into a target chamber filled with a target alkali metal so that it is dissociated into a neutral fragment which is then subjected to charge inversion to generate a negative ion. By measuring the mass spectrum of the negative ion, the isomer can be detected at a higher resolution than has been possible by CID and other conventional mass spectroscopic techniques.
摘要:
An alkali metal introduction apparatus (1) includes: a dedicated fracture chamber (10) and a vacuum chamber (20); vacuum pumps (60a) and (60b) for evacuating the insides of the dedicated fracture chamber (10) and the vacuum chamber (20); an ampul fracturing section for causing, in the dedicated fracture chamber (10), an alkali metal encapsulated in an ampul (16) to be exposed out of the ampul (16) by deforming the ampul (16); a collision cell (40) configured to allow the ampul (16) to be introduced therein, the collision room (40) being provided inside the vacuum chamber (20); and an ampul introducing section (12) for moving the ampul (16) between an exposure position where the alkali metal encapsulated in the ampul (16) is to be exposed out of the ampul (16) thus deformed and an introduction position where the ampul (16) is to be introduced into the collision cell (40).
