Your qst.is not clear.However,AAS can be used to carry out metal analysis,but it takes a lot of time.Because it can detect only one metal at a time and only one sample at a time.

But in case of ICP,it can detect about 25 metals at a time,though the cost is high.

Your conclusion doesn't make sense and can not support your initial statement. How can,for example, 15 elements analyzed by AAS (15 different calibrations, 15 different samples and numerous QA and QC samples, basically the whole day of work) cost LESS than one shot of all 15 elements analyzed by ICP (one calibration curve, one sample, and few QA and QC samples – maximum 15 minutes of work)? There is some fuzzy math in India, or the analyst’s or the lab’s time is considered totally insignificant.
