Sir my many regards to you sir, your videos make me easy understand the concept because of u sir.. love you sir.. U r the best Teacher to everyone... If u give one reply to my comment ..I feel very happy
Both methods can be used for analysis. But some metals having very low excitation energies, so better sensitivity/ detection can be done by emission spectroscopy because emitted radiation is measured.

sir in AAS already flame will be right? using flame itself electrons can exited like in FP then how that radiation source analyse in AAS PLEASE ANSWER ME SIR
50ppm = 50 × 100%/ 1000000 = 0.005% Mol. Weight of KCl = 74.5 Mol. Weight of K = 39 Mol. Weight of Cl = 35.5 So, 50ppm K = (74.5×0.005)/39 = 0.00955g of KCl dissolved in 100ml Distilled water. 50ppm Cl = (74.5×0.005)/35.5 = 0.0105g of KCl dissolved in 100ml Distilled water. Generally KCl will not be prepared as ppm... If you want to prepare then dissolve 50/1000000 g of KCl in 100ml of distilled water.
In atomic emission spectroscopy/flame photometry we determine alkali earth metals and it based on absorption of thermal heat and emission by using flame. while fluorescence is based on lumniscence (emission of light) .
explanation is good.But when you taking about AAS there is an error. After exciting an atom , that will come to ground state or will be ionized..thats not a matter..but when an exited atom comes back to ground state by emitting absorbed energy, that is emission, whether the energy source is electromagnetic or thermal.. how ever you must mention that, when an atom getting exited , it absorb energy.. that energy is used in AAS not emitted radiation.
Sir why you call flame photometry also an atomic emission spectroscopy ? Although in atomic emission spectroscopy different sources for excitation are used like AC arc,gas discharge tube and laser beam etc while in flame photometry only flame is used ....can you explain sir for my guidance pls?
Atomic Emission Spectrometry (AES) is a broader term, of which Flame Emission spectrometry (formerly known as Flame photometry) is one of the type. Some people use them interchangeably. but, it is not the correct one... In Atomic Emission Spectrometry (AES) different types of atomization methods (The process by which sample is converted to an atomic vapor is called atomization) used like Flame, electrothermal, Inductively coupled plasma, Direct current plasma, electric-arc, electric spark etc. were used. In Flame photometry, the flame is used as a method of atomization of a sample. If a solution containing metallic salt (or other metallic compounds) is aspirated into a flame (like acetylene burning in air), a vapor which contains atoms of the metals may be formed. Some of these gaseous metal atoms may be raised to the energy level which is sufficiently high to permit the emission of radiation which is characteristics of the metal (like the characteristic yellow color imparted to flame by the compound of sodium). This is the basis of flame emission spectroscopy (FES) formerly known as Flame Photometry. Reference: VOGEL’S Textbook of Quantitative Chemical Analysis, 6th edition, PEARSON Education, Delhi, page no. 584. So, flame photometry is a type of Atomic emission spectroscopy.
time is changing....all can reach awesome content with no cost....Thank you so much sir....amazing content
Sir,your lecturing level is sooo good..so that I had improved my basic knowledge in Flame emission spectroscopy.Thank you so much sir..
Thank you sir tomorrow is my exam of pharamceutical analysis ur video help me alot
It is possible to cover whole syllabus because of u
Thank u sir
Thank You for the appreciation.

Bestest ever sir in analysis
Superb sir ur very talented person👌👌👌👌👌👌👌👌👌👌
what does ionization energy and flame test of group 1 and 2 elements to do with flame photometry
Sir my many regards to you sir, your videos make me easy understand the concept because of u sir.. love you sir.. U r the best Teacher to everyone... If u give one reply to my comment ..I feel very happy
Thanks for the appreciation
Many many thanks for your reply.. thank you very much sir..
makes much more sense. after watching this video
such a useful knowledge u provides in all your vedeos in few minutes thank you sir keep it up👍👍👍
Thank you so much for your appreciation
Dr. Sir u r amazing plus lecturer plz share vedios as much as u can sir we will study under u as very more vedios that helpfull in all...🤩
Tq sir.. U explain very well tq so much
Sir kya ye meyhod chlorides ke liye bhi use karte h
Thank you so much sir ....Very nice explanation and very helpful for point of exam view
Always Welcome
Can we use a flame photometer to measure the amount of any metal? I read his in an article but then the others say it is only for group 1 and 2.
Sir , apne fluorimetry pe koi video nahi banayi ???? Sir uspe bhi bana do and SEM and TEM pe bhi
Yes, bahut jaldi bana denge.
Haan sir please jaldi banado ek do din tk

Sir...Is it possible to measure absorption radiation in flame photometry?
Respect from Nepal
sir,your videos is blurred in these 2 lectures
Please make video about spectroflourimetry
Sir please use of markers red blue nd related colour
Very nice sir i understand this very simpy
Ca, Na, K, Ba can also be analysed by AAS too so what is the need of AES or flame photometry
can u plz explain littlebit why so
Both methods can be used for analysis. But some metals having very low excitation energies, so better sensitivity/ detection can be done by emission spectroscopy because emitted radiation is measured.
Flame photometry is limited function. However, cost is comparatively very low.

Sir please explain flourimetry also..
sir in AAS already flame will be right? using flame itself electrons can exited like in FP then how that radiation source analyse in AAS
PLEASE ANSWER ME SIR
MJ Techs Wavelength of emitted radiation will be different and that wavelength is selected for detection.
Ohh.. yea sir thank you understood sir
Sir i hv done well in analysis exam.. am soo thankfull to u sir thank u soo much
MJ Techs
Glad to know that my videos are useful for you.
Thankyou sir
I understand easily
Most request sir plz upload more videos related to analysis
Definitely I'm try to upload maximum number of videos
please sir ,provide detail information about introduction,principle offlame emission spectroscopy in hindi
Thank u sir... It help me so much in xam..
how to prepared 50ppm kcl solution
50ppm = 50 × 100%/ 1000000
= 0.005%
Mol. Weight of KCl = 74.5
Mol. Weight of K = 39
Mol. Weight of Cl = 35.5
So,
50ppm K = (74.5×0.005)/39 = 0.00955g of KCl dissolved in 100ml Distilled water.
50ppm Cl = (74.5×0.005)/35.5 = 0.0105g of KCl dissolved in 100ml Distilled water.
Generally KCl will not be prepared as ppm... If you want to prepare then dissolve 50/1000000 g of KCl in 100ml of distilled water.

Sir what is the difference between atomic emission spectroscopy vs fluorescence spectroscopy?
In atomic emission spectroscopy/flame photometry we determine alkali earth metals and it based on absorption of thermal heat and emission by using flame. while fluorescence is based on lumniscence (emission of light) .
IN AAS, ground state gaseous atom absorbs EMR not excited state atom......please correct the explanation
Thank u so much sir. .Good job👍

Instead of using different elements u can use simply electrolytes ..
Okay.... Consider electrolyte in the place of different elements 🙂
