Description
Absorbance-Transmission Excitation Emission Matrix, or “A-TEEM” is a multimodal spectroscopic approach that incorporates UV/Vis and 3D fluorescence for a 2-in-1 measurement. This attractive methodology promotes a rapid and cost-effective alternative for analyses in areas as diverse as water treatment, food & beverage, natural products, and pharmaceuticals. One of the key attributes responsible for its appeal is the very low limit of detection, often in the parts-per-billion to parts-per-trillion range, which is several orders of magnitude better than competing technologies such as NIR, FT-IR, and Raman. In addition to having high sensitivity and specificity, A-TEEM has proven to be a robust tool for samples with complex matrices and analytes of interest that are present at low concentrations, which is often the case for natural products. Separation techniques such as liquid (HPLC) or gas (GC) chromatography tend to dominate in this field, where the components of interest must be separated from the matrix for detection. However, the pitfall associated with utilizing these methods is that they are expensive on a per-measurement basis, as the cost of solvents, columns, standards, waste disposal fees, and annual maintenance fees must be considered. In light of these limitations, A-TEEM has demonstrated the capability to characterize these complex samples prior to separations, which if feasible, provides a significant time and cost savings. Here, we will demonstrate how A-TEEM can be used to rapidly screen samples of lavender essential oil to detect signs of adulteration.
