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..

[@pedrozeinsteger]

Excellente explanation! So easy to understand, congratulations!

[@deepbanerjee5900]

Nice presentation.....I have a question regarding EI.....The wave length of electron having an energy of 70 ev is of the order of 0.14 nm which is some what of the order of a covalent bond you say....However if you check out the bond lengths of carbon carbon single bond (0.15 (c-c)) and carbon hydrogen bond (0.109 (c-H) ) and other covalent bonds the values are quite different....how do you explain that? Do you have any literature reference for this statement...could you please share that???

[@amitkumaracharzo3358]

I appreciate your nice video. Could you please suggest me any good book for better understanding mass spectrometry

[@dipalipatil622]

Very clear concept understand thank you sir

Wow this is excellent

[@techtimes1985]

Great video

[@innovativeetudier4858]

nice explanation

[@ShwetaSingh26810]

Very clear explanation. Can I use some very short clips of your video to make an explanation on MS in hindi?

[@udayakumarkumar9968]

Very very nice HPLC also explain mam

[@srirampmna135]

If a positive repeller r used , does the electron gets attracts to it and reduces the probability of collision with molecules and hence ionisation?

[@marimuthu71]

Excellent

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

[@bebolovesshrek]

MS uses 4 components:
1) heater - which converts the molecules into vapor
2) electron beam- for ionization
3) mass analyzer
4) magnetic/electric field
5) detector

Good

[@studygroup8959]

Nice explanation thanks!!!

[@ianmatthewkline8279]

Thought this was speech generated software at first... no way they gonna program it to say "vaporized" as "way-paw-wized" tho
