Hi Paul,

Are you referring to bulk solder or solder on boards?  If you're not picky,
SEM/EDX or XRF can give you tin/lead composition.  For more detailed
analysis such as solder purity, I would recommend atomic absorption
spectrophotometry (AAS).

Does anyone know of an analytical lab where they can do analysis of
solder down to %0.1 ?

XRF should work, but I am not picky.
