Marshall,

    Interesting that you use a spectrophotometer. Can you tell me how you get 
reference cuvette solutions to graph what your CS sample is. To me, that would 
be the tricky part. You would 0 out with distilled water, but where do you get 
known CS concentrations to plot your readings?

thanks,

doug

  You can get accurate measurements using a spectrophotometer.  That is what I 
use when I need accurate data.
