| Samples were Copper Oxide/Potassium Bromide pressed pellets in the range of 0.01 - 60%. The Authors use a combination of Resonance Lines [324.7nm] and non-resonance lines [521nm] to produce a combined calibration curve. The curve has different linear segments depending on the concentration of the sample under evaluation. | |||||
