Send both solder samples to independent analytical lab who issue C of C
(pay $) with reference standards (e.g ICP detection limit for example).
Settle it once for all.  Qualify a new vendor is part of cost you have
to pay to switch vendor (therefore, unless it got big cost reduction,
the risk for long term consistancy, shelf life, etc.etc. is out weight
the use of the "old chap").  Being said that, you always want to have a
2nd supply qualified.  So go ahead do the job if you have the budget.
If the "new" company will pay for the analysis, that is really good news
for you to get independent assessment at no cost of yours.  This is the
1st time I heard of using competitive vendor as "in-dependent"
analytical work...Wrong choice of yours at 1st place....
