I think Mike has the correct answer.
This way you can at least run a dynamic extraction if your ROSE equipment does this (it should).
 
Another alternative but very tricky on such a large panel is to perform a "bagged extraction" per the IPC procedure (procdure number escapes me) and either run Ion Chromatography (preferably) or run the solution through your ROSE equipment.
 
Brs,
