Mass spectrometry

Mass spectrometry (Mass spectrometer) is the analytical technique that measures the mass to charge ratio of ions. In this technique the sample molecules are converted into ions by several methods such as: electron impact ionisation, Chemical ionisation, or electrospray ionisation. Once the ions are generated they are allowed to enter the mass analyser where they are separated by magnetic field based on their mass to charge ratio.

Sir please add IR, UV, AA Spectroscopy classes too..

[srirampmna]

Excellent explanation.pls keep on adding more videos like this

[wistyeria]

thank you so much, i was worried that i wouldnt get it but now i understand

[chukwurahsomadina]

Thanks a bunch you teach with such clarity .

short summary of the video: Different elements are made of isotopes. to identify different isotopes and their abundance in nature, chemists use Mass Spectrophotometry, a technique which not only informs them about the abundance of an isotope, but also provides crucial details such as mass number, atomic number etc.

Working:
consider a sample of Zirconium passed through the MS.
it is vaporized by the heater.
the vapor then gets ionized by an electron beam source.
the ionized vapors get accelerated between 2 electric plates.
then they acted upon by 2 strong magnets/electric field
here, their kinetic energy remains same, while the difference in movement is based on their mass.
the Isotopes with a greater mass to charge ratio face the least deflection, while, the isotopes with a low mass to charge ratio, face the highest deflection.
the detector detects this and the frequency of the ionized isotopes can be represented in the form of a graph.

the chart is plotted as follows:
along the X axis: Atomic mass (u)
along the y axis : relative abundance (%)

regarding the detection by the detector:
different isotopes are detected at different positions by the detector.
this enables the chemist to plot a chart representing the output obtained
