The analysis of gemstones is demonstrated, using low-power 50W EDXRF with indirect excitation.

In 1970, marijuana was designated a Schedule I drug under the Controlled Substances Act, making it nearly impossible for laboratories to perform cannabis research. However, medicinal use of cannabis is now legal in Canada and 36 U.S. states, with more joining every year. With the passage of the Farm Bill in 2018, it is now federally legal to grow and process hemp in all 50 states. All of this interest in medical cannabis and CBD has highlighted the need for good analysis methodology in this relatively young market. Cannabis analysis is still developing standardized protocols, requirements, and acceptable testing practices. Typical testing requirements for cannabis and its products include heavy metal analysis, pesticide residue, and the potency of active ingredients such as tetrahydrocannabinol (THC). The terpene content of cannabis is also important. Terpenes have been shown to have beneficial uses for treatment of conditions ranging from cancer and inflammation to anxiety and sleeplessness. It is believed that the combination of terpenes and cannabinoids in cannabis produce a synergistic effect with regard to medical benefits, further elevating its popularity worldwide.

Nebulizer selection is a critical but often overlooked aspect of inductively coupled plasma–optical emission spectroscopy (ICP-OES) analyses. There are many different nebulizers available for ICP-OES, and choosing the optimal one can be confusing and difficult. To achieve peak performance from your ICP, it is essential to choose the proper nebulizer based on your sample types in addition to any necessary accessories to maintain long-term performance. In this study, we compare the performance of Glass Expansion’s most popular concentric nebulizer designs for ICP-OES applications as well as a parallel-path nebulizer from another vendor, providing a complete selection guide based on performance and design.

Material identification, also called positive material identification (PMI), is used to analyze and identify materials for quality assurance and quality control to verify proper alloy or material is being used.

The analytical performance of your ICP can often be improved by a careful choice of torch, spray chamber and nebulizer components by taking into account the type of samples that will be analyzed. In this article, we focus on the “hard to measure” ICP-OES elements, As, Se and Pb to determine whether we can improve detection limit performance by selection of appropriate sample introduction components.
