ATR-FTIR Spectroscopy
Attenuated total reflectance (ATR) is the most widely used sampling methodology for Fourier transform infrared (FTIR) spectroscopy. ATR-FTIR quickly and easily measures a broad range of sample types, including liquids, solids, powders, semisolids, and pastes. Learn about how ATR-FTIR works, the different types of ATR sampling accessories available, and their applications.
Learn MoreTransmission FTIR Spectroscopy
Transmission FTIR mode is suitable for liquids, gases, powders, and films. Learn about how transmission FTIR spectroscopy works, the different types of transmission FTIR sampling accessories available, and their applications.
Learn MoreReflectance FTIR Spectroscopy
Reflectance FTIR is used to acquire high quality spectral data from solid samples. Specular reflection is used with reflective surfaces, diffuse reflection (DRIFTS) works with rougher, less reflective surfaces (often powders), and reflection-absorption grazing angle FTIR measures sub-micron thin films and contaminants on surfaces.

Improve ROI with Fast Assessment of Decarboxylation Status in Cannabis and Hemp Extracts
A key step in cannabis oil production is the decarboxylation of naturally produced THCA to psychotropic THC or CBDA to CBD, respectively. This step can be done either before extraction by heating the flower or after extraction by heating the cannabis oil. In both cases, heat is used to speed up the decarboxylation process. But with this heating step come considerations and problems. Excess heat or time will degrade the cannabinoids to unwanted side products, and it will tie up production capacity and generally incur higher production costs. To better control this important processing step, we have developed an infrared (IR) monitoring solution that can track decarboxylation progress in near real-time. We have been able to validate the process for decarboxylation of both THCA and CBDA in both flower and oil. We will present our monitoring solution and the Agilent IR platform that enables this work.
