Great video, simple and informative. Thanks
Thank you very much for this benefits explanations
Thanks for providing accurate information in such a short time ❤
This is the most explanatory video of the principle of FTIR that I've seen so farrrrr😊😊😊. Thank you very much.
Very concise, informative and right to the point!
great explanation
This was straight to the point , precise and very well explained.thankyou
Cool video, clear and logical! Thank you a lot!
Super helpful. It clarified a lot of misunderstandings. Thanks!!
Very crisp and loaded with information
Thank you...this knocked twenty years of dust like nothing!
best video for learning FTIR. on the net
Thank you for providing such easy and crisp information
This was great !! Thank you
A very useful video for beginners, Thank u so much!!!
Short, clear and concise
Really important and impressive video of all the time, thank you!
You are a genius. Thank you for your clear explanation
Great video. Thank you!
Informative and clear.
very insightful! thank you so much for the knowledge.
Superb video .... Great job .... Thanks for uploading 😊
Very good, thank you!
Nice video, very clear, thanks!
This Is so helpful.thank you
Very nice and concise, I real like it bravo
Mantap penjelasannya bro
Very helpful and a great explanation of how it works
Thank you
You're welcome!
Excellent. Thanks!
Very well explained
In a nutshell , perfect!
Nice information
Kickass
❤
Great video! Can you explain what the purpose of the laser in FTIR is?
same question here.
The laser is used to guide the FTIR source
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.
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?
Great
thumbs up if galing ka sa class ni sir Bryan!
great thank you
It's our pleasure to provide clear and educational content.
0:36, the unit of wavelength should be in meter, not in nanometer.
please make another vedio LC FTIR chromatography
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"?
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!
Do we get to know functional groups attached on a chemical by means of FTIR?
Yes! This is actually one of the main purposes of collecting infrared spectra.
@@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.
Please how long does it take to prepare and run samples using FTIR
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: th-cam.com/video/qTH8wmI-5lw/w-d-xo.html
does ftir helps to find out the percentage composition of any compound say pet in wihich ?% of tpa and ?% of ethylene glycol
...?
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: th-cam.com/video/U6386R7w3Kc/w-d-xo.html th-cam.com/video/doAf8xPoiBI/w-d-xo.html
How is the method used to determine D2O vs H2O?
Hi Rawdiswar, we have a video for that: th-cam.com/video/5GCj7EwaRrg/w-d-xo.html
How much the penetrative thickness of the composite filling materials??
Could you elaborate?
Nice
Thanks
love your German accent
Dividing? you meant subtracting right?
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".
share me this video
So this is how they're going to test my drugs I sent off
Great video, Thank you!
Very well explained
Glad it was helpful!
