One of the Cannabis Science Conference (CSC) Fall speakers is Autumn Phillips, who works as a Research Chemist and Chemical Hygiene Officer at Inorganic Ventures. She shares more about her background in cannabis science in this conference preview.

ICP-OES can accurately measure the elemental ratios necessary to optimize battery performance and improve recycling efforts so that battery recoveries are optimized. The authors explore how ICP-OES can help manufacturers meet the increasing performance demands required for lithium-ion batteries.

Glow discharge (GD) spectroscopy is a well-established method in the elemental analysis of metals, coatings, and surface-modified materials.

Using internal standards is a common technique to correct for variations in sample matrices and the effect this has on analyte intensities. There are several basic criteria to be considered when using internal standards: selection of appropriate internal standards, the concentration added to the solutions analyzed, setting up in the correct view (axial vs. radial), how to introduce the internal standard to the solutions to be analyzed, and evaluating the resulting data. Each of these topics are considered and suggestions presented.

A team of researchers has conducted a successful round-robin test using total reflection X-ray fluorescence (TXRF) to analyze the elemental composition of rat tissue samples. The preliminary results demonstrate the effectiveness of TXRF in accurately determining the elemental composition of mammalian tissue.

Researchers have developed a method for the simultaneous determination of cadmium and lead in water samples using microwave-induced plasma optical emission spectrometry with multiwalled carbon nanotubes pre-concentration and a discrete sample introduction system.
