Establishment of a Working Curve

Any good analytical working curve requires first the establishment of optimum operating conditions, including spectral line selection, fuel and oxidant selection and control, sample uptake rate, and the positioning of the optical path and optical components. Once established, these conditions must be maintained throughout the acquisition of the analytical data. 

The simplest analytical system to deal with is one in which the background is zero or very low and there are no spectral interferences of concern.
