Before taking any action suggest you resample your pot, ensuring that
you take a sample which is representative. Something like this: turn
pot on allow to get to temp. After machine has been operating for an
hour or so take a sample from the wave itself and chill it rapidly. If
you really do have a high tin content like this you would most likely
have already noticed it in results, would not need to have an analysis
to find out. Quite an important question would then be how did it get
to be like this??
