Any mass spec could. But you'd have to really consider which ones are probable, and what configuration they are going to be in. I'm not sure if Mass Specs fragment metal complexes like AcO[M], so you may have to take that into account as well.
And if you DO ionize them and fragment them, theres no way to know what their parent complex is.
And to be honest if you use spring or tap water, the amount of metals in there is going to be huge... not sure how you would narrow down which metal is contributing to the taste.
