Hi Joel, DCHA is soluble in most organic solvents. Be sure, however, that your solvents are dry. Even a very small amount of moisture in the solvents can cloud your KBr cell windows.

Wouldn't there be residue of the solvent in the cell? Do we just leave it to air-dry?
@PIKETechnologies
@PIKETechnologies Год назад
Thank you for your question, @wildreams. To avoid residue/contaminants, be sure to use an ultra-clean, spectroscopic-grade solvent. To dry the cell, I like to use an empty syringe and push air through the cell to speed the drying process. 😉

The AR coating would not absorb IR radiation, or the absorption bands would be negligible?
@PIKETechnologies
@PIKETechnologies Год назад
Hi @mirceadanpuia9688, We use a broadband AR coating, which provides a nice wide range and does not interfere with the mid-IR spectral range. If you look at the energy throughput spectrum shown at the 1:40 min mark you can see small signatures due to the coating, but these will ratio out. 😊

Hi Martim, When ratioing your sample spectrum to your background, contamination, for the most part, will cancel out if you are diluting at a very low concentration. Feel free to reach out to us via piketech.com with more questions! :)

Thanks for the tips! Any thoughts on sloping baselines for particle samples? I've gotten severe sloping on gold nanoparticle deposits that I could never resolve. I think I once read that this could be from scattering by the particles? Not sure if this is related to the critical angle issue you mentioned or a different phenomenon.

@PIKETechnologies
@PIKETechnologies Год назад
If you are seeing fringing using a liquid transmission cell with ZnSe windows, the easiest resolution is to consider a lower refractive index window relative to ZnSe---this will significantly reduce fringing. You can see an example of an aqueous sample here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sawHHgsFx5U.html You are always welcome to reach out to us directly and we can discuss your sample and spectra further!

My experience is that ATR correction should particularly be used when acquiring spectra for compounds that contain OH or NH groups as the absorbances for these functional groups will be very low without these corrections.

@PIKETechnologies
@PIKETechnologies Год назад
Hi Sena, My guess here is your sample is not compatible with the window material. Perhaps you are using a soluble salt window like KBr or NaCl when there is moisture in your samples, and this is causing the foggy, cloudy window. That said, keep in mind even when a window is a little cloudy you can still get good transmission through it! Even when the window does not look as pretty, it is still usable!

@PIKETechnologies

Hi Cam, There are some low-absorbing samples that will require a higher concentration like 5%. I typically start at 1%. If my absorbance bands are too small I bump up the sample concentration. If too big I reduce the concentration. You can learn more about making the perfect pellet recipe here: tinyurl.com/4bymn4wb

What windows can we use for aqueous samples
@PIKETechnologies
@PIKETechnologies 2 года назад
When choosing a window for IR liquid transmission cells, consider a window with the best solubility, sample pH, spectral range, and I like to stay with a low RI window when possible to minimize fringing in the IR spectrum. You may find that you need to make compromises. You can see window properties in our Theory and Application note, www.piketech.com/wp-content/uploads/PIKE-Technologies_Transmission_Theory_and_Applications.pdf

Thank you for your question! Definitely try the Kramers Kronig transform when you see derivative-shaped bands to make the spectrum appear more transmission-like. For coatings and ultra-thin films on reflective substrates, often the spectrum will already appear like a transmission spectrum, and no transformation is required.
