Product description
- When determining iron in an aluminum alloy, ∆S=0 corresponded to the concentration С0 Fe = 0.23%, and for the standard with the concentration С1=0.54% ∆S1=0.60. Build a calibration graph and determine the percentage of iron in the test sample if ∆Sх=0.32. (S is the blackening of the lines of the homologous pair in the spectra of the standard).
