UV Visible Spectroscopy

In this video, we will look at the principles and apparatus involved with UV-Visible spectroscopy, and show how it can be used to quantitatively analyse a sample to find its concentration.

thank you so much.It was very helpful with my midterm test XD

[@mohammadyousaf8001]

A very informative description

[@pictmon]

Great explanation! Many Thanks!

so the sample absorbs the light? ive been reading on uv vis spec, and what ive come to understand is that the sample absorbs the light, but it can also excite the electrons in the sample as well im trying to understand how uv fitr etc work with gemtone analysis, when the gems absorb the light this would theoreticaly change the makeup of the gem yes? if it absorbs the radiation and if the beam ecites electrons in the gem wouldnt the gems structure change slitely?

Nice job!

[@viswanathgowd4060]

nice explanation...

[@msalman464]

merci, monsieur bien!

I think it would be a better order if you ran the standard solution (known concentration) to create a standard curve before measuring the unknown samples. Less confusing for students.

its really nice

I hate videos that are ruined by the speaker stuttering or smacking their lips or swirling their tongue in their mouth.

Christopher Daly II they forget about editing. Its not like they are teaching 1 plus 1 math videos...

[@mohit189]

Not a good explanation

[@Simha20048]

Please..want clarity.and not good explanation

[@hawaramli4]

not a good explanation. but thumbs up for the effort. but please improve.
