In case of optimizing serum zinc concentration through Flame Furnace in Atomic Absorption Spectrometry (AAS), some of the precautions I try to ensure in lab, are:

  • Dilution of the serum: as flame furnace demands larger volume comparing with graphite furnace; supplied serum sample perhaps be limited then it remains a big challenge.
  • Cleaning of the plastic (or acryline materials) and glassware materials related with the experiments is a very crucial task. After finishing each experiment, I clean up the materials using detergent almost twenty times, then wash them by tap water, then with de-ionized water, then keep them in 6N nitric acid solution (acid in deionized water) for 24 hours, after that washing with ion-free water again and finally keep them in 1N nitric acid solution. These are the steps I follow in my lab for washing.
  • In case of machine operation (AAS) I follow every step according to the cook book and manual.

    • Question for those who research mainly in analytical chemistry field, what should other precautions be which I need to maintain for zinc analysis?
