Part 14: Mass Spectrometry - Double Focusing Mass Spectrometer | Analyzer

[@haiderali3418]

You really helped us alot in quarantine, our teachers have only given us the notes and marked the topics, but without your videos, I can't understand the topics, everything was looking too much tough, love from Pakistan 🇵🇰🇵🇰🇵🇰🇵🇰, keep it up sir

[@pkclasses100]

Glad to know 👍🏻 Thank you for the appreciation. Keep studying and Share the Video Links with your friends and help us to spread the knowledge. ❤️💜💙💛💚

@@pkclasses100 yes sure sir, our whole class is watching your videos, and clearing the concepts, great work

[@Warda-tul-Naqashbandia]

May God bless you. I only watch your videos to learn mass spectrometry.. Thanks for making it easy and understandable. Lots of prayers and best wishes.

Sir..I have no words to appreciate you..really your lectures are so great

Thank you so much for the appreciation

thank you sir..........one day before exam😀😇

Dr.Pushpendra doing a great job, but also work on accuracy! When you accelerate ions, say with a voltage of V, Kinetic enrgy of all the ions will be 1/m(v squared). working backward, velocity of each ion will be inversely proportional to the square root of the mass of the ion. thus low mass ions will be much faster than heavier masses! Sure magnetic deflection mass analyzer is a momentum filter. It only means that all the ions of same momentum take a arc which will have the same radius. Thus they all travel along the flight tube and enter the slit and travel on to the detector. as m1v1 will not be equal to m2v2, in the normal case, as we scan the magnetic field, one after the other ions reach the detector and get registered.

Sir you are doing great job... I love your videos... Ty for helping us... ❤️

Thank u sir..tomorrow is my instrumentation exam..it will more helpful for me☺☺☺☺

All the best. 👍

[@karunasagardheram598]

I missed on one thing, 1/2 * m(v squared). When mass difference of the ions becomes very small, it could happen that m1v1 becomes equal to m2v2 and such ions can not be separated by magnetic deflection alone. When we apply the electrostatic analyser, ions of identical enrgy are filtered and now as eE=1/2 * m(v squared), only ions of a sigle KE can pass through and m1v1 can never be equal to m2v2 and interference gets removed or as you say we have much better resolution! I hope you take it in the right spirit.

Dr. Dheram I request you to kindly upload more refined and accurate video on the Mass Spectrometry, So it will be highly useful for all of us. With Regards

[@karunasagardheram598]

I'm sorry, you've taken offence. I very much appreciate your efforts and only wanted you to make further improvements. It's certainly people like you who are really helping our students along. @@pkclasses100

As per my opinion you are working with BARC as scientist on MS and specialized for that. These videos are for UG and PG students. If I will give complicated material then it will not be that much useful. If anyone wants to study that much specified then he/she will study from reference books. We are trying to give basic knowledge, if anyone wants more or questions arises in his/her mind then I will suggest them to explore by themselves.

Mass analyzer is separate part excluding detector or detector is also component of mass analyzer? as analyzer+ detector= mass analyzer

[@shaguftaaleem1395]

Magnetic sector or double focusing mass Analyzer dono same hi cheez hain ?

[@sudhirmauryaji]

Thank you so much 👍

[@nanotechnology107]

Aa dear respected sir, please let me know what ions will be detected first by detector having m/e unipositive charge 10, 20, 30 in double focussing mass analyzer and simple magnetic mass analyzer?

[@rashmishukla6864]

Very nice explanation sir..and sir plz add one more topic effect of fragmentation..in Mass spec..plz.. :)

How come the abundance of M+ is the highest yet you drew it as the least (in spectrum) compared to the lower abundance of m1+ and m2+?

[@haiderali3418]

Sir have you uploaded the video of detectors of mass spectrometry, is it? Then please send me the link, I'm the student of BS chemistry final semester, my exams are very near, only 8 days left.

@@pkclasses100 at 5:30, i dont understand why the ions with the higher mass reach faster as opposed to those with a lower mass because i would've thought it'd be the other way

[@pkclasses100]

@@Qurann21 due to less deflection in higher mass ions it happens, but only in ToF it will be like that whatever you are saying.
