Single-Compound Isotopic Analysis of Organic Materials in Archaeology
LCGC Europe
Isotopic analysis of archaeological materials provides information on age and source, but analysis of single compounds isolated from artefacts can provide more accurate measurements and additional details. In this article, the authors provide a review of chromatographic separations of archaeological biomolecules for their analysis using accelerator mass spectrometry or isotope ratio mass spectrometry. The article concentrates primarily on studies involving carbon and nitrogen.
Maximizing Cannabinoid Separation for Potency Testing with LC
April 7th 2025Researchers from the Department of Chemistry at Western Illinois University (Macomb, Illinois) conducted a study to optimize the separation of 18 cannabinoids for potency testing of hemp-based products, using liquid chromatography with a diode array detector (LC–DAD). As part of our monthlong series of articles pertaining to National Cannabis Awareness Month, LCGC International spoke to Liguo Song, the corresponding author of the paper stemming from this research, to discuss the study and its findings.
What Goes in a CDS IT Service Level Agreement?
April 7th 2025Protecting your network chromatography data system (CDS) data is critical and a service level agreement (SLA) with your IT provider is vital. What should be included? Are SLAs for in-house IT and SaaS (software as a service) similar?
