I learned today that we have a sequential electrochemical reduction
analyzer (SERA) made by ECI.  Are there any other makers of this kind
of instrumentation?

Back in the distant path of my undergraduate chemistry training I
remember cyclic voltammetry with beautifully resolved reduction
curves, not at all like the low resolution DC reduction curves I've
seen so far.

Is SERA testing becoming (or has it become) the accepted method for
qualitative analysis for solderability?
