Mass Spectrometry

009 - Mass Spectrometry

In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass spectrometer are detailed including the ionizer, mass analyzer and the detector. A simulation of Chlorine isotopes along with an average atomic mass calculation is included.

Wow, you've taken something that I assume is incredibly complex, explained it in 8 minutes and I actually understood it.
And I sucked at chemistry.

You are such a thorough teacher and what you do for thousands or even millions of students is absolutely amazing. Thank you for all your efforts!

[TheJoshtheboss]

Bozeman Science and KhanAcademy are pure blessing. Thank you guys!

[صادقرياضصادق]

wow man you deserve to call you a doctor in your field !
a real person who understand the whole concept and explained it very simple you're not a teacher you're from my point of view a learner

Thank you so much! This was wonderful. I'm writing a paper on identifying biomarkers for pancreatic cancer and specifically researching apolipoprotein A. Thanks so much for going step by step for me to better understand the MS process!

Thanks, I use this video in my lecture on atomic mass. I like that you showed the calibration of the machine, the whole process makes more sense when you see what can go wrong with analyzing a sample.

The analogy with the car/motorcycle making a turn was brilliant. Thank you!

Can he be my chemistry teacher please?

[dirackfield]

Easily the best intoduction to the topic on youtube

Oh thx i am 13 yrs old and i decided to learn about mass spectrometry and it really helps me. Thanks again

[TheEpicGod]

Undeniably the greatest of all time Mr. A.

[yansirreaviles]

Thank you so much Mr. Andersen!! You are seriously the best. I needed to understand this for my MCAT review and just could not wrap my head around my Kaplan book or AAMC explanations. However, your explanation finally made sense to me. Thank you again, from the bottom of my heart.

I wish I had that kind of teacher in university :) Simple and interesting explanation of method sometimes difficult to understand .

[Guidus]

what a superb explanation this was, some of these videos are a work of art from an educational standpoint

[scottyinspiar]

I can't believe this doesn't cost money! THANKYOU!!!

[yvngac]

GOAT Science youtuber along with crash course

[zetasky]

Every other video totally confused me with its complexity, but this one totally cleared it all up! Thank you!

[Friends_]

You are a god sent. Thank you very much for helping us out. You do really have a great talent in teaching and presenting. So thank you for not keeping it to yourself.

[mariansyk]

Thanks <3 Sometimes I think why I go to the uni...

[shalusingh]

I would also like to know how to read a mass spectrum and how to identify various peaks.
