The Principles of ICP MS

[@kingsleyseow4715]

As a college freshman, I'm watching this video and thought to myself, how did human beings thought and engineered such an intricate instrument? The human brain is amazing

[@dummysalami]

Same! And meanwhile, I'm here struggling to understand this concept haha

[@vergaburro2613]

As a college graduate student, I thought the same thing.

[@idw9159]

Like most of science it came step-wise. First scientists discovered electron beams in gas discharge tubes and then realized that the electrons came from atoms/ molecules which had developed a positive charge. JJ Thomson devised the mass spectroscope to study these charged atoms/ molecules and found they had different trajectories through electric or magnetic fields - discriminated by their mass/ charge ratio. This was 100 years ago and gave the first evidence for isotopes (20-Ne and 22-Ne). Over a century technology has improved but the principles are the same - ions separated by their mass.

And a “simple” prokaryotic cell is infinitely more complex than this. Nature is insane

[@topkekfilmproductions3464]

I like how this is 240p, thanks

[@sujathapikki911]

exactly

[@seyna2037]

01:38 is where the explanation of the technique starts

[@aniruddh-chakravorty]

The only video I could find in youtube which actually explains the working concept without showing off there product and bla bla... ICPMS videos are very less . Also video quality could have been a lot better.

[@sapnupua5]

a very concise explanation, good video.

[@frankreiserm.s.8039]

I can't believe how much the He gas cleaned up the data. Unlike the "5110 icp-oes demo " video, I'm g;ad that this video was in English. Frank Frank's Beautiful Rocks and Minerals

[@sayantansaha1976]

Makes ICP-MS but cannot make HD videos. Congrats.

[@fmcsoccer7688]

Salvage 😅😂

[@paulferry7791]

I would imagine the one doing the voiceover for the video is reading from a script. I wonder how much of what he is saying is something he is wholly familiar with as well.

[@atrumblood]

The poor quality of the video aside, this is very informative.

[@ss11nlM]

7500 is an old instrument..

[@samregan9613]

What would be the effect of analyzing too many compounds (metals for example)? I've experienced that when too many metals are being analyzed it can lower the signal of each of the metals, but why is this?

[@Leo-ii8nb]

I think it depends on the quadrupole. It is limited by the amount of changes of m/z a second. If you are analyzing too many compounds, the right m/z is not often set enough. Many ions won't be stabilized and therefore not reaching the detector

[@thuler_lima]

Would you have the script for this video to translate into Portuguese? Thanks ;)

[@kevindelgado7083]

Wow 2 anos e ainda nada -.-

[@SamsonSalopuka]

This diagramatic explanaition is very interesting❤

[@jayraj5361]

as for mercury wat type of matrix is best, the nature of the sample like meat and rice

[@adamnewman5357]

for determination of mercury in meat and rice check out Milestones DMA 80 instrument

[@arnolddowney9807]

I believe food samples are often digested in a heated mixture of acids, and the final matrix is something like 2% HNO3 6% HCl after diltution. Although, I've mostly seen Mercury analyzed with atomic absorbance instead of mass spec. I'm sure either works fine though.

[@surprisingly]

Yeah, but how do you clean it?

[@i_teleported_bread7404]

Man, I was just looking for Insane Clown Posse music, I watched the whole thing and I still don't know what this thing does...

[@dj69321]

It's used to test cannabis products for heavy metals contamination before it's sold to you at the dispensary! Among other uses.

[@aserioussalamander9475]

is this as good as thermo fisher?

[@jhankaar941]

Is the trace element detect there or any method to know the heavy quantity of element

[@xavierxrc]

Did you have a stroke?

[@petsandfamily3944]

Tienen en español para el 5110 ICP-OES, preparación de standards/misread/qué blanco, etc.? Explicación de cómo usar la computadora para obtener resultados, etc. Gracias

[@arunkumarshrestha4546]

Can we measure radioisotopes such as 238U,232Th and 40K using this ICP MS?

[@vetomelgoza4249]

Yes

[@cherrycorn666]

Fuuuccck we need that in our lab🥹we already have an expensive ICP without helium mode… running calibration standards every time before testing samples is so painful!!!

[@junnileromero170]

Can ICP-MS be connected to Extraction chromatographic column?

[@Teamwork001]

Dangers from using that cause ... seizure, coma, stroke, or brain damage... Have fun! 🤙🏼

[@KingCosmo7]

I understand a good deal of this, but it still sounds like gibberish with that tone of voice, lol

[@oakohcan]

Wassup smart people

[@山田なお-j7b]

日本語訳が欲しい

[@agilent]

This is what we learn in elementary....so sad and disappointing that you cant make your own content...
