Examples of assays using AAS

AAS is used principally in limit tests for metals in drugs prior to their incorporation into formulations. The sample is generally dissolved in 0.1 M nitric acid to avoid formation of metal hydroxides from heavy metals, which are relatively involatile and suppress the AAS reading. 

The calcium (Ca) and magnesium (Mg) in a haemodialysis solution were analysed 

The dialysis solution was diluted from 5 to 250 ml before analysis of Ca 

Thus the concentration of Cain the diluted stand d solution = 1.07 mg/100 ml.
