We are running an Electroless Nickel/Immersion Gold line, one bath of
which contains Ruthenium.  We use a Varian Spectra20 AA to measure the
Ruthenium via method of additions.  I recently purchased a new burner to
be used solely for this line.  The machine was inspected early this
year.  Two analyses of the same sample yield values of 67 and 147 ppm
(the specification is 125 ppm).  Frustrating.

Does anyone know another method that I can use to measure the Ru?
Thanks.
