This past week, LCGC International published a variety of articles on hot topics in separation science. We discuss how mass spectrometry (MS) unveiled new insights into how music modulates protein networks in lipid nanoparticle delivery and how gas chromatography (GC) can be sed to identify aroma types in unburnt cannabis. Also, we make a call for nominations for the 2026 HTC Innovation Award.

In this interview segment, Christian Mayer discusses the benefits of using pressure cycling to study prebiotic chemistry.

LCGC International spoke to the author of the study, John Mommers, who is a scientist of chromatography and mass spectrometry (MS) at Envalior, about the key challenges faced when developing MASSISTANT and how it can be integrated in GC-EI-MS workflows.

A recent study examined a new method to optimize raisin production by demonstrating how pretreating grapes with extra-virgin olive oil (EVOO) before dehydration can significantly improve the retention of beneficial phenolic compounds during raisin production and storage.

This week, LCGC International published a variety of articles on hot topics in separation science. From several interviews around the role chromatography is playing in forensic analysis to using multidimensional liquid chromatography (LC) in the development of a new Python tool, we’ve highlighted some of the most popular articles that were published this week.

As part of “From Sample to Verdict,” LCGC International sat down with Noemi Procopio, who is the Principal Investigator of the "Forens-OMICS" team and a Senior Research Fellow in Forensic Science at the University of Central Lancashire to talk about her team’s work. In Part III of our conversation with Procopio, she discussed how her team analyzes bone samples for post-mortem interval (PMI) estimation. In the final part of our conversation, Procopio discusses what a routine omics-based PMI assay could look like in the future.

As part of our “From Sample to Verdict” series, LCGC International sat down with Furton to discuss his team’s work in the Global Forensic and Justice Center. In Part II of our conversation with Furton, he discusses the applicability of SPME in other forensic applications, as well as the limitations of using SPME.

As part of “From Sample to Verdict,” LCGC International sat down with Noemi Procopio, who is the Principal Investigator of the "Forens-OMICS" team and a Senior Research Fellow in Forensic Science at the University of Central Lancashire, to talk about her team’s work. In Part I of our conversation with Procopio, she discussed the development of the Forens-OMICS approach and how her team estimates PMI using metabolomics, proteomics, and metabarcoding. Part II dives deep into post-mortem interval (PMI) estimation and how bone proteomics can be used to accurately estimate PMI.

As part of “From Sample to Verdict,” we present a compilation of the latest news articles and peer-reviewed content that highlight the utility of chromatography in forensic analysis.
