[@Polymershik]

A very useful video for beginners, thanks a lot! P.S. Could you tell me, please, what substance IR spectrum was shown at the end 4:27 of?

[@shindemaster3084]

Nice information

[@lindseythurston2035]

Great video! Can you explain what the purpose of the laser in FTIR is?

[@abdulalemalkhawlani7571]

same question here.

[@richard180961]

The laser is used to guide the FTIR source

[@Bruker]

The laser beam travels alongside the IR beam through the interferometer and generates its own interferogram. This is then used to measure the interferometer displacement (optical path difference) and calibrate the X-axis of the spectrum with very high accuracy.

[@harmandeepkaur5245]

please make another vedio LC FTIR chromatography

[@yogitabasnal]

Do we get to know functional groups attached on a chemical by means of FTIR?

[@Bruker]

Yes! This is actually one of the main purposes of collecting infrared spectra.

[@yogitabasnal]

@@Bruker so u mean different fucntional groups will give different IR spectra? Actually during my dissertation I could not do this technique because the instrument was not working, I was supposed to do this. I did TEM, X ray diffraction etc but could not do SEM and FTIR.

[@venkataradha.o4918]

great thank you

[@Bruker]

It's our pleasure to provide clear and educational content.

[@secondhandpictures8523]

thumbs up if galing ka sa class ni sir Bryan!

[@limjunjia3829]

The paper I'm reading states the FTIR spectrum indicates low damage caused during processing. I'd like to ask how does FTIR spectrum indicates "low damage"?

[@Bruker]

Dear Lim Jun Jia, The question and info is very vague - but let's interpret "low damage" as "low amounts of damage done to a material or product", e.g. a polymer work piece. For example, you can assess the "damage" that has been done by oxidation due to sunlight or the chemicals the work piece was in contact with, if it is a container. Here, an FT-IR spectrum will clearly show the oxidation by AIR for example in many polymers. So maybe, similarily and depending of the paper your reading, this is meant by indicating damage, as it might change the chemical setup of the material. Hope that helps!

[@cathycharles3528]

does ftir helps to find out the percentage composition of any compound say pet in wihich ?% of tpa and ?% of ethylene glycol ...?

[@Bruker]

Hi Cathy, in general FT-IR is capable of analyzing even complex mixtures and it is especially suited for the analysis and quantification of polymers, blends, copolymers, etc. In your specific case (PET), however, I can't give you a final answer since each case must be tested individually. Maybe these videos helps you to learn more about FT-IR and polymer analysis: kzbin.info/www/bejne/i2eWaWmIbNxmgcU kzbin.info/www/bejne/mqCkl2uuhdSceKs

[@adetola20]

Please how long does it take to prepare and run samples using FTIR

[@Bruker]

Hi Olanike, we have tons of videos showing how to prepare and run samples using FT-IR. If we are talking about a solid or simple liquid, preparation, measurement and evaluation takes roughly 1 minute - total time! For reference, take a look here: kzbin.info/www/bejne/p4WraaqjfpJootk

[@huangjingle8342]

0:36, the unit of wavelength should be in meter, not in nanometer.

[@jithinjob5381]

Great

[@ayahasim8491]

How much the penetrative thickness of the composite filling materials??

[@Bruker]

Could you elaborate?

[@Rawdiswar]

How is the method used to determine D2O vs H2O?

[@Bruker]

Hi Rawdiswar, we have a video for that: kzbin.info/www/bejne/a3imm2p7rMaFqMk

[@skiphoffenflaven8004]

Kickass

[@sabinahasanova7198]

love your German accent

[@mahneh7121]

Dividing? you meant subtracting right?

[@Bruker]

Hey Mah Neh, dividing is correct. Here's a quick resource for you: www.ncbi.nlm.nih.gov/pmc/articles/PMC4327635/ However, if you want to analyze sample mixtures, you can subtract a pure spectrum proportionally from the mixture spectrum and reinterpret the remaining signals, also called "Residual Spectrum".

[@unholyjesus]

So this is how they're going to test my drugs I sent off

[@wenyizhou9500]

Great video, Thank you!
