Lead Detection Using Flame AA Spectroscopy

[@trevorbeardsley1989]

"Can't believe you guys trust me with this instrument," the words of a true chemist.

this really helped me understand so I could write my procedure for my design using the aa spec, thanks :)

Thank you ❤️😃 Fans from Sri Lanka 🇱🇰😃

great video, might want to clean that burner head though.

[@arifindobson]

Very interesting, regarding the flame color, is it possible to run Machine Vision rather than spectroscopy to measure the samples. Very curious about it

[@yienemolla4075]

can AAS detect adsorption of lead(white in color) without complexing agent?

[@MrMoomooballs]

what is the name of the liquid you used before and in between measuring samples to clean (and i guess calibrate?) the aa spec?

[@andyg160]

AWah are you still looking for an answer? I can help you out

[@miriaaamly6833]

@@andyg160 yes please!! what's the liquid??

[@ShadowMe77]

The deionized water?

Hola! Tengo una consulta técnica sobre ese equipo.. creen que puedan ayudarme?

[@RandalSutton-x7q]

Could you please tell me how to prepare the sample?

[@timecode37]

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).

Hi, What is solution to clean the flame H2O or CHL 25% or NaCn or what ? Tnks

[@osuchemistry458]

+Rachid Bouassou The blank solution to “clean the flame” is ultra-pure (MilliPore) H2O.

[@rachidbouassou]

hi, software version spectaa 5.4 not work after 60 day plaise help me for solution thnck you.

[@mishackmushi2312]

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

[@DD-gb2qy]

Why we get much fluctuations while taking readings!??

[@douglasrocha2515]

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.

[@douglasrocha2515]

Aside from this, 2-5% SD on readings seems pretty acceptable to me.

[@Platingisfun]

DON"T TOUCH ANYTHING HERE!!! Lol, must be a chem lab in college. BTW clean your burner.

[@jota4488]

limpia el mechero

[@jaivervalencia5666]

your burner-instrument is dirty.
