Very interesting, regarding the flame color, is it possible to run Machine Vision rather than spectroscopy to measure the samples. Very curious about it
Hey guys help me here I am yrying to analyse bismuth using FAA from a lead powder...how do i separate bismuth from the lead powder so i can get the bismuth solution and be able to run it in the aa
As far as i know you need to get the analyte into solution, and in a way so that you can easily vaporize and atomize the sample (for example, many sulfates or phosphates wouldn't be ideal as you'd need a lot of energy to get them to vaporize. Chlorides might be a viable method if you want to go for AAS). Depending on your analyte you may even need a different setup for your spectrometer (think cold vapour aas for mercury).
It can be either: 1) some dirt clogging the solution path to the nebulizing chamber; 2) light source is not properly adjusted (low signal to noise ratio) or the lamp is getting old; 3) reading consecutive solutions without proper rinsing and/or delay time.
