Calculating the gold content in a solder pot is a good effort but
difficult.  A solder supplier or independent lab can test samples
periodically.  This data is useful to monitor the solder pot as well as
refine any empirical model.

Subject:        [TN] Gold contamination!

I Technetters,

I have a question about the Gold-Nickel coating.
I want to know if I will have a gold contamination
problem in the solder wave?
If yes, how I must calculated the number of
boards wich pass before I must change the solder?
(or time..)

Note: I have an automatic solder refiller and I also
Know the limit of gold (0.2%, ANSI/J-STD-001A table 5.1)
but that's all!

Thanks for all for your help
