Description Attenuated total reflectance (ATR) and Fourier-transformation infrared (FT-IR) portable device. Same principles than the FTIR-ATR technique non portable.
The analysis is performed by placing a small amount of unknown substance in solid form onto the diamond ATR sensor. The sample interface also includes an integrated well for the containment of liquid samples. A second, touch-to-sample, diamond ATR interface is available for rapid analysis of pooled liquids and surface films. Unknown substance are authenticated by comparison with library reference spectra.
 
Strengths Rapid;
Non-destructive;
No sample preparation needed;
Objective analysis of the product (contents analysis);
Portable;
Relatively easy to use;
 
Limitations Requires specific equipment: the device and some training for the person who is manipulating the device;
Cost;
Reference spectra needed;
