Truly Exceptional

[@williammutwiri2370]

that was a clearly detailed video ,i wish you could do one on ICP'S

[@ahmadfares5243]

Excellent, well explained, short, clear, complete 👍👍👍👍

[@LynetteNekel]

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 ]

[@ScienceReady]

Our videos are actually based on the NSW HSC syllabus 😊

[@LynetteNekel]

ohh that makes more sense :D@@ScienceReady

[@johnlouismemoryschooltamil5275]

Simply excellent. Thank you

[@vishalmangaraj]

Very detailed information, thank you 😃

[@brendakimaiyo5563]

THANK YOU. IT WAS VERY HELPFUL.

[@mawadamarei2703]

Thank you, I have an exam tomorrow and this saved me!

[@chemistrypk5425]

Well-done

[@Haseebsaleemi97]

Love this

[@青蛙呱呱-r5z]

Very clear

[@sistermorphine7874]

Great video

[@brightontome2305]

well explained sir

[@k3_izhanggiobayuzhedha193]

u save me ✨👍

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

[@rassimsimou1594]

Good

[@OMNI-Infinity]

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

[@OMNI-Infinity]

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]

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]

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]

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

Got chem exam in 2 days :)

[@samermoussallem9949]

Does AAS only analyse metal concentrations?
