Mass spectrometry

[nagaraj835]

hai this is very excellent explanation through view nature of the enter smaple into the MS-speoctrometry instrument, Thank You

[vapourphaze]

speak up

[anu262713]

it relay help us to understand MS.

THANK YOU

[sherifmohamedtaha]

good as a fast introduction on lCMSMS.

THANK YOU

without some explaining words this is useless.

@tomsan84 this shows the operation of a Fourier transform mass spectrometer with a front end electrospray source. (1) mass specs require gas phase ions to work. from 0-20 you see ions being made. 2000 volts beween the tube and the inlet will direct ions into the MS. liquid phase ions (like sodium+ chloride-) are turned to gas phase by heat and gas.... when the droplet becomes small enough, the (+) ions push away from each other and are now in the gas phase and go into the MS.

its incredible how brilliant people can be

Marvelous

m/z is mass to charge ration, fyi

[dkw62]

This is a Fourier Transform Ion Cyclotron Resonance Mass Spectrometer. The sample is actually being ionized utilizing electrospray ionization, so not a solid sample. FFT means fast fourier transform. QB/m is how one goes from a frequency spectrum to a m/z spectrum. and there is no sounds with this.

Interessante em 3D!!!

[faizn]

is it not ment to have sound?

[chandnee]

its awesome ! so wonderful, I couldh've never conceived it better ! Thank you so much for uploading this video...especially for a nube like me .

[bordway]

this is wierd to see the 2kV applied to the nebulizer...must be a solid sample?? I've only seen that charge (2kV) applied within a continous dynode where the ions would have enough kinetic energy after passing threw the quadrupol to multiply electrons as it hits the dynode... could u explain the sample entry for me?

[lewisjames1990]

when the graphs are shown at 1:16, whats does FFT and qB0/m mean?

[proteowizard]

@lewisjames1990 FFT = "fast fourier transform" it refers to a math algorithm to take a composite analog signal and give you the discrete frequencies that make up that signal... So, if you required a "C" chord played on the piano you could pull out the frequencies of the 3 notes....

[hboy007]

very nice ! finally a video about a quadrupol mass spectrometer

[juansillero]

how was made this video??????? With 3D studio max???
