The Mass Spectrometer | Physics with Professor Matt Anderson | M23-19

If I shot some charged particles into a magnetic field, they will bend their trajectory. But how much they bend depends on their mass. So maybe I could make a cool device out of this to determine the mass? Genius! Oh wait, it's already been invented.

How does he write on the board so it's legible for people in the front? does he write backward?

was thinking the exact same thing!!

So, the detector(s) determine the 'r', and it uses that to calculate the mass..? Because the mass is the unknown. I'm going to have to read more about this to see how the particles are liberated from a sample. I've used spectrometers that sweep through wavenumbers from 0 to 2(pi) to check all possible transmissions through optical samples. The goal is to check max transmission per given wavelength.

Correct. Crazy invention but totally works.

Thank you so so much. My professor explained this horribly. Now there is some hope for my exam.

You are an awesome teacher thank you💞😊

[@parmmohan4603]

If you know the mass then you can identify the matter. Brilliant!!!

[@yoprofmatt]

Pretty cool, eh?
Cheers,

@@yoprofmatt Very cool! I assume you need different detectors for different materials and this method only determines the isotope
