    THANK YOU SO MUCH I COULDNT FIND ANYTHING ABOUT THE AAS PROCESS [also ik this is from the US but its helped an ATAR student from the land down under ]

      Our videos are actually based on the NSW HSC syllabus 😊

    Question.. why you convert ppm tô mg/l? Ppm IS a partes It means volume and mg IS the Wright. Pb 1ppm of volume IS not 1mg pelo litet. Pls comment

    Does AAS only analyse metal concentrations?

    Here's a thing I don't understand. Wouldn't the flame produce light and 'contaminate' the absorbance reading?

    • @OMNI-Infinity
      @OMNI-Infinity 2 роки тому +2

      And also, how does heating up gaseous metal bring metal atoms into ground state? By intuition, it should increase the energy level of the electron right?

    • @ScienceReady
      @ScienceReady  2 роки тому +1

      Yes that's correct, however spectrometers will often take a "baseline" reading of any contaminant light and remove any of those matching wavelengths from the reading of the detector.

    • @ScienceReady
      @ScienceReady  2 роки тому +1

      The electrons will relax and return to the ground state on their own after they have been excited by energy provided by the flame

    • @ScienceReady
      @ScienceReady  2 роки тому +1

      @@OMNI-Infinity Usually they will simply take the reading for just the flame itself without the metal sample in it first.
