The ability to determine the statutory classification of cannabis rapidly and cost-effectively is critically important to the cannabis industry, from growers to formulators and manufacturers. THC content is the single piece of information that determines the legal status of a crop or finished product. The quantification of THC is most often obtained by HPLC, a slow and expensive method when compared to spectroscopy. At the same time, most spectroscopic methods – NIR, FT-IR, and Raman – struggle to meet these statutory limits, due to issues with sensitivity and specificity. In this webinar, we will present a better way to determine cannabinoids in hemp and cannabis, using a combination of UV absorbance-transmission and fluorescence excitation emission matrix spectroscopy, called “A-TEEM.” In particular, we will show that: 

The simultaneous use of UV absorbance-transmission and fluorescence excitation emission matrix spectroscopy (A-TEEM) provides a sensitive, specific, reproducible, and repeatable method for the qualitative and quantitative characterization of cannabinoids in solution.

The limits of quantification (LOQs) of the A-TEEM method are comparable to those of HPLC, with high values of cross-validation and prediction for chemotype identification.

Using photons instead of physical separations for component identification, A-TEEM has the benefits that make spectroscopy so attractive for rapid screening: fast (<60 s) measurement times and low per measurement cost.

Introduce the A-TEEM spectroscopic method, which combines UV-Vis absorbance with multidimensional fluorescence.

Highlight the unique attributes of A-TEEM for detection of low-level components in complex mixtures, specifically cannabinoids in simple methanol extracts.

Show the benefits of using A-TEEM as an alternative to HPLC for this analysis and other natural products.

It would not be too much of exaggeration to state that Physics and Materials Science research of the first half of the 21-st century is being shaped by the amazing discoveries of 2D materials such as graphene, transition metal dichalcogenides (TMDs), black phosphorous and their heterostructures, both vertical and lateral. Raman spectroscopy and hyperspectral Raman imaging is extremely efficient for characterization of 2D materials. Quite often, the scale of structural or electronic or morphological heterogeneity in these materials, not to mention their heterostructures, is on the order of few tens of nanometers or less, which is beyond the spatial resolution of conventional Raman microscopy.

Tip enhanced Raman scattering (TERS) and tip enhanced photoluminescence (TEPL) can enhance the spatial resolution. In this lecture we’ll -

Demonstrate how TERS and TEPL imaging can probe a number of nanoscale heterogeneities in 2D crystals: growth related, including lateral and vertical heterostructures, substrate induced, and the morphological heterogeneities that appear (intentionally or not) in the process of exfoliation/ 2D crystal transfer.

A single technique is not always sufficient to fully characterize a sample. The information will be much more complete by combining complementary data. The critical point is to be sure to perform the tests on exact the same area of the sample. Thanks to co-localization, this is now possible. During this webinar we will show on different applications the interest of combining Raman and µ-XRF characterizations with this co-localization tool.

Micro-particles are used extensively for a wide variety of applications including food and agriculture, pharmaceutical, and advanced materials manufacturing. While traditional particle size analyzers can provide information on particle size and shape distribution, chemical identification is not possible using techniques such as dynamic light scattering, for example. Raman microspectroscopy combined with automated particle analysis tools provides a complete picture of micro-particles, including both morphological and chemical characterization. In this webinar, the technique of particle correlated Raman spectroscopy (PCRS) will be presented, and will be illustrated by representative application examples from fields including forensics, pharmaceuticals/cosmetics, and microplastics. Included will be a discussion of handling and preparation of a variety of sample types including powders, tablets, and suspensions.
