Thank you for sharing the link. I found it really useful cause to me it wasn't clear the relations between measured and desired isotopic ratios. For example, how does the IRMS software derive the isotope relations from delta 45, 46, 47... given there are 9 isotopologues.
Mass spectrometers like this one are used to determine the ratios of certain isotopes or compounds. In the case of this video the spectrometer is being used to determine the concentration of “light” vs “heavy” CO2. If you look at the graphic on the left, you’ll see there are three different examples of CO2, all with different masses. (See the Carbon-13 and Oxygen-18 being used in the second and third) Since these isotopes of Carbon and Oxygen have a higher mass than our CO2 with a Carbon-12 and two Oxygen-16s, these CO2 compounds will also have a higher mass, thus they will be affected less by the magnet when shot through the flight tube.
Thank you, I've been looking for a video that clearly explains this process!
You're a life saver ! I'm definitely gonna use this for my exam. Thank you!
Very clear video, thank you !
Small video with all explanation.....nice one.

what is this machine used for. Whats the exact purpose?
