A spec turns a sample into a plasma and measures refracted light shown
through it at a given frequency.
A colorometer uses a pre calibrated chemical reaction "pillow" specific
to silver and compares colors the solution turns with the chemical reaction.

From what I can gather, to measure ppm with a spectrophotometer you
must measure a solution with a known ppm first. You then measure the
unknown solution and then using a formula you can calculate the ppm of
the unknown solution. If you have multiple known solutions of CS of
different ppms, you can plot a conversion chart that gives more accuracy
than the formula. Is that correct?
Does the colorimeter use the same methodology?
Thanks,

Find a lab that has a flame spectrophotometer and knows how to use
it.
The Hach Colorometer [like Ole Bob had] works pretty well
Titration processes normally used in water analysis are wildly
inaccurate at 10 PPM.
