Atomic Structure - Time of Flight Mass Spectrometry｜AQA A Level Chemistry Revision

Physical Chemistry #3 (Year 1 Revision) 3.1.1 Atomic structure

This is intended to be an ultimate guide and revision video on the first section of the 3.1.1.2 Mass number and isotopes sub-topic under the 3.1.1 Atomic structure topic for the AQA A-Level chemistry specification. The aim of this video is to help all of you revise and prepare for your paper 1 and 3 exams.

I teach you everything you need to know for the following points:
◼ The principles of a simple time of flight (TOF) mass spectrometer, limited to:
→ ionisation
→ acceleration to give constant kinetic energy
→ ion drift
→ ion detection
→ data analysis.
◼ The mass spectrometer gives accurate information about relative isotopic mass and also about the relative abundance of isotopes.
◼ Mass spectrometry can be used to identify elements.

Hi, just wanted to let you know since i just got a notification from you and was reminded, thank you for making your videos! I found yours the most useful out of anyone elses. I managed to get an A after getting C’s for all my mocks. Tysm!

[sneakysneakers]

i’m so confused as to why this is not included in other videos when covering this part of the spec idek had to learn this

[Kyeremeh]

Could you make a video on the c and H nmr (nuclear magnetic resonance)

[nameisinused]

how do you remember all of this 😭i am so bad about memory things

Thank you for the clear and concise video, you have helped me greatly in studying for my atomic physics class.
