- This video explains the principle of Inductively coupled plasma-Atomic emission spectrometry or Inductively coupled plasma-Atomic emission spectroscopy. It also explains the instrumentation and working of Inductively coupled plasma-Atomic emission spectrometry (ICP-AES). It also explains the applications of ICP-AES.
You will be able to
elucidate the principle of inductively coupled plasma-atomic emission spectroscopy (ICP-AES).
explain the instrumentation and working of ICP-AES.
list out the applications of ICP-AES.
Principle of Inductively coupled plasma-Atomic emission spectrometry ICP-AES :
Excitation of atomised metal with inductively coupled plasma, followed by emission of light of its own characteristic wavelength and the correlation of the emitted light with the concentration of the metal is Inductively coupled plasma-Atomic emission spectrometry (ICP-AES).
Used to detect trace metals in ppm
Nebuliser converts liquid solution to fine particles of aerosol/mist
Solvent gets vapourised leaving behind the solid residue.
The solid residue gets vapourised to gaseous form due to high temperature of the plasma and the molecules dissociate to atoms.
The metal atoms get excited to higher energy level .
The excited metal atoms emit light of its own characteristic wavelength by returning back to the ground state. (Ni- 393nm, Cu- 325nm Na- 589nm, Li 670nm, Ca 622 nm, Ba-554nm).
Instrumentation & Working of Inductively coupled plasma-Atomic emission spectrometry ICP-AES.
Source - Plasma is an electrically neutral conducting gaseous mixture (cations and electrons). It is heated inductively by coupling with an oscillating magnetic field (radio frequency). The temperature of the plasma may be of the order of 5,000 to 10,000 K - eg. plasma torch.
RF generator - Radio frequency generator creates the RF signal and intense electromagnetic field is created in the induction coil when the torch is switched on. A plasma at temperatures up to 10,000 K is created due to an ignition of a spark from a Tesla coil (the seed electrons from the Tesla coil oscillate in an angular path and periodically collide with argon gas atoms and ionize them, releasing more electrons. Due to their kinetic energy and collisions with other atoms a large amount of heat is generated, enough to generate and sustain a plasma).
Nebuliser and spray chamber - Converts the liquid sample to mist and sprays the fine particles along with argon gas into the plasma.
Atomiser - Converts the analyte molecules to gaseous atoms, which gets excited and returns back to the ground state by emitting light of its characteristic wavelength.
Monochromator - Polychromatic light is dispersed into individual wavelengths e.g. diffraction grating , Rowland circle, etc.
Detector - The intensity of light with different wavelengths is measured using (i) a set of photomultiplier tubes (generates current proportional to the intensity of the light) or (ii) fall on the array of semiconductor detectors such as charge coupled devices (CCD’s), photodiode arrays etc.
Data processor and display - Data from these detectors are processed and multiple wavelengths are measured at the same time (higher the concentration higher is the intensity of emitted light ).

Happy that it helped you and you liked it.
Mam ur amazing.. first time iam listening ur class.... Iam. Addicted😍😍
Thank you very much for compliments.
Thnks for such a informative vedio..... explain in a good way..,👍
Thanks for your compliments.
This is such a good explanation.
Thank you.
thank you soooo much, the BEST explanation even better than my teacher, god bless you keep saving lost student.
Thank you so much. It's my pleasure.
Thank you so much for such a beautiful explanation ma'am🙏🙏🙏
It's my pleasure. Thanks.
Thank you so much for the informative information
You are most welcome.
Is this type of analysis can determine all type of meteorite?
So helpful...Very well explained ma'am...Thank you
Thank you. It's my pleasure.
awesome explanation
Thank you so much.
Thank yu mam..🙏🙏Now i understand ICPEAS
It's my pleasure.
appreciable initiative
Thank you.
Thank you so much for this
You are most welcome.
Your explanation is very good❤🎉
Thank you.
Your explanation method is amazing🙂
Thanks for your compliments.
Make more vedios about analytical chemistry ... I'm student of MPhil chemistry
Thank you mam for making explanation so simple.
You are most welcome. It's my pleasure.
Thank you for this lacture...it is complete detail lacture that i want ...and i get it Thankuuu
Most welcome.
Thank you so much😍 clear and good presentation❤️👍

Very well explanation ma'am
Thank you very much.
Thank you it was very beneficial this is gonna extremely help me to prepare my graduation thesis so
can i know please the sources or links from where did u bring your informations because i need to mention them on it
Thank you very much.
My internship is going to be about this and it's a little more complicated than just plain LC or GC or xRF apparatus. So this is going to be interesting
Thank you very much 😊
👍
Thanks
Clearly understood Ma'am
Ma'am can you plz make video on ICP- MS
Glad that you have understood. Sure, I will do.
Icp ms ku notes erundha send panunga sister pls clg la seminar eduka theva padudhu pls help panunga pa🙏🙏🙏🙏🙏🙏🙏🙏
Good
Thank you.
I have question....Only argon gas atoms with tesla seeds atom play role to make plasma(by Colliding) ....in middle tourch conpartment also there is sample metal atom.....is there no influence of there?....
Sample is in the centre tube only. Plasma will be created in the middle cylinder. There are three inlets.
@@RevathiPurushothaman yeah ....got it
Thank u
Great explanation Mam.... can you please make video on ICP MS..
Sure.
Sister icp ms ku notes erundha send panunga plss clg la seminar eduka enaku theva paduthu konja help panunga pls🙏🙏🙏🙏🙏🙏🙏🙏🙏
It was best!❤🙃
Thank you very much.
Superbbbb
Thank you very much.
Madam nebulizer and atomizer are same device? Or if it different, where are nebulizer and atomizer located in the instrumentation?
Madam I understand nebulizer convert liquid into mist and atomizer convert molecule into atoms.
I have read this that nebulizer and atomizer are same.
So kindly clarify this.
Also, the way you explain the things is wonderful. Thank you .
In the nebuliser, the sample gets converted to a mist and then it finally gets atomised in the atomizer.
Ok ma'am thank you for replying.
Is it same as ICP-OES?
Almost same except for the detector.
Can you please mention the reference of the images / information provided
I created the image using bits and pieces along with my own colouring.
Mam icp aes icp ms these two are same or not? Could you explain what is the difference between icp aes, icp ms pls clear my doubt mam its my humble request. 🙏🙏🙏
Both are different. The principle is same for ICP. You may watch the video on Mass spectroscopy. ICP-MS is the combination of both ICP- MS
Nice ma'am
Thank you.
Gud mam. Wat is emittiing characteristics of own wavelength
Each element will emit a particular wavelength called it's characteristic wavelength
@@RevathiPurushothaman Not a wavelength but many.
Love from Pakistan 🇵🇰
Thank you very much.
What's the diffrence between icpaes and icpoes
Both are same
Can you send the schematic to me
Hi
Why result came in saturation
I did not understand your question.
@@RevathiPurushothaman we will check titanium content in cadmium titanium plating solution, in that solution 40 to 100 ppm titanium requirement
We analysed in ICP-OES method result came staurated
Please give answer
Can you please suggest the sources from which you have taken the notes. It would be really helpful for me
Multiple sources. I cannot give specifically.
Mam please put the video icp ms mam 🙏🙏🙏🙏🙏🙏🙏🙏🙏
Sure.
@@RevathiPurushothaman thanks 🙏🙏
Plzz can you make detail video plz
Good
Thank you very much.
