How does a spectrophotometer work? 

This video is 100× better than a 15 minute video trying to explain the same concept.

I believe that in the future, videos like these should 'do the talking' in classrooms, especially when the topic is complicated. The professor explains very well but in this case could not be better than a simple, yet effective video. *(P.S. this video summarized my professor's three-month explanation.)*

Wow this was a sweet and informative video. Thanks so much for making it. It made it crystal clear how a spectrophotometer works.

So I'm just here doing some chemistry work, this is like the first and shortest and most informative video with a mega helpful link. love you guys

Brilliant! Crystal clear and straightforward. It helped a lot; Thanks!

Great short and simple explanation. Thanks!

This is so awesome. I love it when educational videos are concise.

This patent is like a forgotten principality that measures the spectrum of ignition refraction of when all things were one and to return back in time where all things have become separated.

thank you, really simple, quick and easy to memorise info!!

Very nice explanation

Really simple explanation, just what i needed for my exam!

simple and clear outline...thank you

I was studying for hours about spectrophotometer.. But this One minute is better than those 👌🏼

A clear and concise explanation.

omg thx! i just got my first "ooooooh" of how spectropotometer actually works lol

thanks! finally something understanable

best and easiest explanation ever

This is so cool. Thank you.

Very useful, thank you!

What is measuring the absorbance of the light by the sample worth for? What important information does that give?

This video made spectrophotometry concept so clear 😙😍😘

How simple and smart device ,thanks sir.

That's because of reflectance : Absorbance + Transmittance + Reflectance = Incident Intensity

I don't usually comment but this video is sooooooo beautiful!

Really simple breakdown :)

Really helpful! Thank you so much

Good video. It explains it well. Just use the Beer-Lambert Law to calculate what you want from the lab with a spectrophotometer :)

This is much better than our school textbook and quora

Thank you for your help

Thanks you've solved my homework ;)

Excellent

Oh! I recognize it now! Little Specky doing his thing! That's what we used to call him Little Specky...

brilliant explanation, thanks alot

If you know the initial intensity and a wavelength of light that bounces off the diffraction mirror, why do you need 2 parameters (absorbance and transmittance) to be measured? Why can't you just measure the transmittance and then calculate the absorbance? Besides how can you measure something that have been absorbed by the sample?

Great video

Thank you for this 👌

Not explained is why you do that. The light stopped by the sample and the light allowed to pass tells us what is in the sample.

Great video

OMG xD i did not notice that you could rotate the diffraction raster >.< this explains a LOT :P made so many exercices wondering how they switched to other wavelengths ^-^

Thank you!

marvelous well done sir

Thank you

Thanks for sharing 🙏

Thanks

Thank you 💞

Shout out to Mr. Rasheed!

Thanks!

Thanks for nice video. Please upload next

Good video

really good!

oh everything makes sense now. thank you

thank you

Very clear 😍

look a sample absorbance is measured to find out the amount of product of a particular reaction (with a colour change off course)... and it is measured against a reagent blank.so , we get : optical density of coloured product = (sample tube optical density - blank optical density) and also a standard o.d is measured against a particular known amount of sample ... so , if we know that 1 ug of chemical X gives 0.523 o.d at say 450 nm of light then ??ug chemical X gives 0.023 o.d .. got it???

This is everything I need in life pray for my physics test tomorrow

Thank you

very nice

Thank you!

thank u so muck I need it from my science fair proyect

SHOW! Thanks

I wonder if you could combine this with computed tomography to get slices of absorptions in pigments?

Thanks alot❤

0:47 Broadcasting into a digital display....#NanoTag #Optics #CNT #HumanTransceivers #HumanAntenna

What if we put a funni orange crystal in it?

how can absorbance be used to determine which solution (if you are testing many solutions) can be used to determine which has the darker or lighter shade of that particular colour?

that's what i was wondering. what's the answer?

thank you.

Good

that's sound good 🙋

simple but sufficient.good jod

Hi bionetwork, would you allow me to translate your video in french and use it in my class in college?

Do you think it is possible to use a similar equipment to identify the element composition of a metal surface?

So I take it that it just test the outside of the object, not telling you if it is solid, ___________. Or does it? thanks

.....And that digital display, can it be converted in to visual display instead of just numbers too?

What exactly is a buffer used for?

Is it related to solubility test?

Ohhhh thank you so much

Hi,may i know the OD displayed is the transmittance or absorbance?

hmm.. beer can you tell one material from another using a spectrophotometer. does it only work on targets on which there is transmittance

nice!

that is awesome )))

Just saved me reading through time consuming manuals.

Does anyone know what is causing the diffraction grating to rotate though, like is it the wavelength being adjusted?

Plz update it clearly

nice

nice

Hi, what program/software was used to make this video? Thanks in advance!

You saved my IB

Why only a specific wavelength should reaches the exit slit ?? 0:18

Don't you need a beam splitter?.

0:09 works like a prison or prizm

Wow

Does anyone know how a dual wavelength spectrophotometer works?

ty~~~

Anyone know of a RGB organic spectral data base?

Hİ There, May you please send me text information, I can not translate because there are many technical words. Best Regards
