Mass Spectrometer - Interpreting Spectra

A heavy topic but a one which will gain you marks! Watch this video to find out how spectra can be interpreted when you have molecules. Find out how to identify fragments and the need for high resolution mass spectrometry and GC-MS.

I don't know why it's been so hard to understand from everyone else. You made it very easy! Thanks a bunch!

Best chemistry teacher I have come across in 7 years!! No word of a lie!!

[Artenuga]

I'm in Advanced Ochem at my uni and my professor's method of teaching is saying "you should know this by now." But I never fucking learned how to interpret Mass Spec. This video helped me out so much, thank you so much!

[emilyfarrell]

Thank you, found this video extremely helpful. You have a great way of speaking so that what you are explaining is very clear. Will definitely use you videos again :)

Chris Harris, you're a lifesaver!

[anesu]

You are so amazing!!!Wow like I don't even remember how my teacher ever introduced this topic recently it's not that I have forgotten but I just never understood what was happening. And she thought she was explaining it the best way she can are literally my life saver, I thank God I found you out just before my exams. Thank You, keep up the good work. It is helping a lot!!!

My final Ib examination is around the corner and I watched this. This is extremely helpful. May God bless you sir

[krishnanarayanan]

You saved my life. I am sitting a Year 13 chemistry assessment tomorrow for spectroscopy. Thank you so much! From, a New Zealander downunder.

literally a legend saying thanks from northern ireland

[blizzard]

This is just excellent, helped me a lot for my test tomorrow!

[ningan]

I actually get a chem final tmr.. and ur video is REALLY THANK YOU!!

[KARBALA]

Thanks a lot I watched many videos all was confusing but yours was so clear

[meltansz]

Sorry if this sounds dumb but I saw how when mass fragmentation took place the molecular ion fragmented into a radical and a cation (from the previous vid) so how would we get CH2+ because that's right in the middle. So even if an electron is knocked off how would we get CH2+ and what would be the resulting radical? Thanks again for all these great vids! :)

[rajuon]

Excellent video. thanks for detailed explanation about fragmentation (separate video) and interpretation of MS

[afnanm]

I asked about this for a whole month now, but wow!

[maishalosker]

hey Mr. Allery
thanks for all the helpful videos so far. I was wondering if you do unit 3 practical ones, we're doing the paper one & it seems tricky

[ayoubsyed]

Hello Chris Harris hope you are doing well, i wanted to inquire if you do unit 3 Papers practical skills as you have brilliant helpful unit 2 tutorials.keep the fab work going !

[Freedomboy]

great explanation. very hard to find good resources in this. My orgo teachers dont even teach anything. we all have to be self taught. We dont even get practice problems that match the very difficult exams. I have not found one resource online that matcg his crazy synthesis problems

[shrutishete]

do we only calculate difference between molecular ion peak and previous peak? or do we need to do it for all the peaks? Thanx.

[mdffmfff]

@allery chemistry shouldnt the peak at 46 be a molecular ion free radical ?
