Product description
2. Below are the results of photometry of magnesium solutions on an atomic absorption spectrophotometer with burners differing in optical path length L.
L=2.4cm
СMg, μg/ml 2 4 6 8 10 12 14
A 0.118 0.325 0.362 0.480 0.594 0.710 0.839
L=4.8cm
СMg, μg/ml 1 2 3 4 5 6 7 8
A 0.113 0.230 0.341 0.457 0.575 0.680 0.805 0.918
L=2.4cm
СMg, μg/ml 0.5 1.5 2.5 3.5 4.5 5.5 6.5
A 0.091 0.275 0.453 0.638 0.809 0.986 1.170
Is the sensitivity of magnesium determination proportional to the length of the optical path of the burner?
