ATR Crystals
Innovative Silicon Crystals for ATR-FTIR
The IRUBIS Single Reflection Cystals are suitable for Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy.
All products can be used with standard FTIR devices.

Universal
Basic Single Reflection
ATR Crystal
The basic version of our crystal has the same performance as a single bounce diamond crystal and a broad spectral range. The short optical path makes the fingerprint region accessible.

Specialized 1
Low Penetration Depth
ATR Crystal
This crystal has a high angle of incidence and thus a reduced penetration depth. This version is suitable for various applications such as Surface Enhanced Infrared Absorption Spectroscopy (SEIRAS).
You can find the IRUBIS technology in different collaboration products.



Auto ATR
ATR Microplate Reader
In cooperation with PIKE Technologies, we developed AutoATR. This device allows the measurement of 24 samples within one run.
J1
Spectroelectrochemical ATR Cell
The J1 by Jackfish SEC is a complete three-electrode electrochemical cell for ATR-SEIRAS using our optimized crystals.

How can we help you?
ATR CRYSTAL
What is the spectral range for the ATR crystals?
You could find some example spectra here. The ATR crystals are suitable for the range 900–5000 cm-1.
How can I clean my ATR crystal?
For organic substances you could use Peroxomonosulphuric acid. For other substances it’s possible to clean them with ethanol or isopropanol. Please make sure, not to exert mechanical pressure.
Can I measure solid samples with my ATR crystal?
Please use the ATR crystals only for liquid samples. They are 0.5 mm thin and not robust for mechanical pressure.
Are gold coatings or other coatings applied to the IRUBIS ATR crystal?
No, the ATR crystal is delivered without any coating. Please check if the following publication “Hybrid Gold–Conductive Metal Oxide Films for Attenuated Total Reflectance Surface Enhanced Infrared Absorption Spectroscopy” that was performed with our ATR crystal might be helpful for you.
What kind of ATR crystal should I use for my SEIRA or electrochemical experiments?
For these experiments most customers use the Specialized 1 ATR Crystal because of the lower penetration depth.
OBSIDIAN ACCESSORY
How could I get the Obsidian Accessory?
Unfortunately, IRUBIS don’t sell the Obsidian Accessory any more. Please send us a message to get DIY instructions.
How can I use IRUBIS ATR crystals on VeeMax?
To use our crystals with VeeMAX you lay them on top of the plate with the small hole. For a fix mounting please use our ATR crystal in combination with the IRUBIS Obsidian Accessory and a 2”x3” holder.
