ICP-OES as a Viable Alternative to ICP-MS for Trace Analysis: Meeting the Detection Limits Challenge

Let’s meet Cannabis Science Conference (CSC) Fall speaker Autumn Phillips, a Research Chemist and Chemical Hygiene Officer at Inorganic Ventures. CSC 2023 will take place from September 20–22nd in Providence, Rhode Island.

Meet the Cannabis Science Conference Fall Speakers: Autumn Phillips Discusses Cannabis Testing for Heavy Metals with ICP-OES

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.

Using ICP-OES to Improve Lithium-Ion Battery Performance and Reduce Waste

Aaron Acevedo is an assistant editor for LCGC and Spectroscopy at MJH Life Sciences.

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.

Key Points to Remember When Using Internal Standards for Sample Analysis by ICP-OES 

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.
