Very interesting, regarding the flame color, is it possible to run Machine Vision rather than spectroscopy to measure the samples. Very curious about it
Thank you ❤️😃 Fans from Sri Lanka 🇱🇰😃

Could you please tell me how to prepare the sample?
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).
Why we get much fluctuations while taking readings!??
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.
Aside from this, 2-5% SD on readings seems pretty acceptable to me.
Great Tutorial 👍🏻
Really great content ☺️... Lobe from India
DON"T TOUCH ANYTHING HERE!!! Lol, must be a chem lab in college. BTW clean your burner.
"Can't believe you guys trust me with this instrument," the words of a true chemist.
your burner-instrument is dirty.

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
can AAS detect adsorption of lead(white in color) without complexing agent?
limpia el mechero
Oh my...
Hola! Tengo una consulta técnica sobre ese equipo.. creen que puedan ayudarme?
great video, might want to clean that burner head though.
Hi, What is solution to clean the flame H2O or CHL 25% or NaCn or what ? Tnks
+Rachid Bouassou The blank solution to “clean the flame” is ultra-pure (MilliPore) H2O.
hi, software version spectaa 5.4 not work after 60 day plaise help me for solution thnck you.
what is the name of the liquid you used before and in between measuring samples to clean (and i guess calibrate?) the aa spec?
AWah are you still looking for an answer? I can help you out
@@andyg160 yes please!! what's the liquid??
The deionized water?
this really helped me understand so I could write my procedure for my design using the aa spec, thanks :)
