Hi Salman,

Explain your question with more details. I guessed that you will not need to follow the graphite, because mey be this elements concentration may be higher in the herbal. Then you will easy to follow the Flame AAS.

If you have to facility to microwave digestion, that is easy. Or else you will able to take 0.5 g sample in pollypropylene tube, then add 0.5 mL HNO3 and put 2 hrs in water bath, 90 C. Then follow the AAS

Salman Ahmed

Please share published protocols (research papers / review articles) of Graphite lamp and Flame AAS regarding herbal.
