Applications of AAS:
Atomic absorption spectrophotometry is now a routinely and hugely employed method for trace and ultratrace analysis of complex matrices of geological, biological, industrial or environmental origin. The atomic absorption methods using flame are rapid and precise and are applicable to about 67 elements. Electrothermal techniques of analysis on the other hand are slower and less precise; thus, these are more sensitive and required much smaller samples. Let us take up some applications of AAS in different areas. We start along with biological samples.
