Modern Instrumental Methods of Analysis

In the last slide, I had explained to you that majority of the elements may be atomized around 2500 to 2800 Kelvin; both pretreatment and atomization curves must be optimized as a function of the absorbance signal. So, pretreatment temperature should be as high as possible without losing the atoms in the atomization stage. Similarly, atomization process should be the temperature of the atomization process, should be as low as possible, so that the life of the graphite tube will be extended.
