short summary of the video: Different elements are made of isotopes. to identify different isotopes and their abundance in nature, chemists use Mass Spectrophotometry, a technique which not only informs them about the abundance of an isotope, but also provides crucial details such as mass number, atomic number etc. Working: consider a sample of Zirconium passed through the MS. it is vaporized by the heater. the vapor then gets ionized by an electron beam source. the ionized vapors get accelerated between 2 electric plates. then they acted upon by 2 strong magnets/electric field here, their kinetic energy remains same, while the difference in movement is based on their mass. the Isotopes with a greater mass to charge ratio face the least deflection, while, the isotopes with a low mass to charge ratio, face the highest deflection. the detector detects this and the frequency of the ionized isotopes can be represented in the form of a graph. the chart is plotted as follows: along the X axis: Atomic mass (u) along the y axis : relative abundance (%) regarding the detection by the detector: different isotopes are detected at different positions by the detector. this enables the chemist to plot a chart representing the output obtained
MS uses 4 components: 1) heater - which converts the molecules into vapor 2) electron beam- for ionization 3) mass analyzer 4) magnetic/electric field 5) detector
Nice presentation.....I have a question regarding EI.....The wave length of electron having an energy of 70 ev is of the order of 0.14 nm which is some what of the order of a covalent bond you say....However if you check out the bond lengths of carbon carbon single bond (0.15 (c-c)) and carbon hydrogen bond (0.109 (c-H) ) and other covalent bonds the values are quite different....how do you explain that? Do you have any literature reference for this statement...could you please share that???

This has become one of my favourite animation educational videos on YT.
thank you so much, i was worried that i wouldnt get it but now i understand
Very clear explanation! So far is the best I found!
Very simple but informational and clear, thanks a lot!
simple illustration, easy to understand, thank you!
Hats off to your Explaination. I wish you were my lecturer
I keep coming back to this video for revisions. Good job!

Great explanation. Thank you so much
You are the best👏👏👏TH-cam have really great tutors than colleges.
Sir please add IR , UV, AA Spectroscopy classes too..
Excellent explanation...❤❤❤
Excellent explanation.pls keep on adding more videos like this
Thanks a bunch you teach with such clarity .
Top notch video and demonstration.
Very impressive and informative...
I am subscribing to learn more
Clear explanation. Well done👌
very nice method of teaching. Keep it up.
Very clear concept understand thank you sir
Wow this is excellent
Awesome content 👏👏👏👏, thanks for uploading 🤗
Very helpful and clear interpretation. Thank you!
Great video
Very very nice HPLC also explain mam
Great presentation. Thanks.
short summary of the video: Different elements are made of isotopes. to identify different isotopes and their abundance in nature, chemists use Mass Spectrophotometry, a technique which not only informs them about the abundance of an isotope, but also provides crucial details such as mass number, atomic number etc.
Working:
consider a sample of Zirconium passed through the MS.
it is vaporized by the heater.
the vapor then gets ionized by an electron beam source.
the ionized vapors get accelerated between 2 electric plates.
then they acted upon by 2 strong magnets/electric field
here, their kinetic energy remains same, while the difference in movement is based on their mass.
the Isotopes with a greater mass to charge ratio face the least deflection, while, the isotopes with a low mass to charge ratio, face the highest deflection.
the detector detects this and the frequency of the ionized isotopes can be represented in the form of a graph.
the chart is plotted as follows:
along the X axis: Atomic mass (u)
along the y axis : relative abundance (%)
regarding the detection by the detector:
different isotopes are detected at different positions by the detector.
this enables the chemist to plot a chart representing the output obtained
MS uses 4 components:
1) heater - which converts the molecules into vapor
2) electron beam- for ionization
3) mass analyzer
4) magnetic/electric field
5) detector
Fantastic video . Thank you for lecture.
How to make protein molecules neutral before the electrons hit it ?
❤❤❤❤
I appreciate your nice video. Could you please suggest me any good book for better understanding mass spectrometry
و الله يسطا انت جامد فشخ
Very Clear
Thankyou so much ❤❤
Very clear explanation. Can I use some very short clips of your video to make an explanation on MS in hindi?
If a positive repeller r used , does the electron gets attracts to it and reduces the probability of collision with molecules and hence ionisation?
oh is interesting 👏💯
nice explanation
thanks a lot

Excellent
Good
Nice explanation thanks!!!
Love from India(•‿•)(•‿•)♥️
Thank you 😊 it helps a lot
Thought this was speech generated software at first... no way they gonna program it to say "vaporized" as "way-paw-wized" tho
spec-TROM-etry not spectro-MET-ry 🙄 duh
