In Memoriam: Anthony Macherone
It is with great sadness that we acknowledge the passing of Anthony Macherone, PhD.
Anthony Macherone, PhD., an Analytical Chemist for Agilent Technologies, was a valued member of our Editorial Advisory Board and a highly experienced expert in the field of cannabis and hemp testing and analysis. He led a team of scientists in the development of analytical methodologies to support research, safety, and quality control for the emerging cannabis and hemp fields, and has written extensively on cannabis testing, contributing to several chapters to books about cannabis. His recent articles published in Cannabis Science and Technology include, “How Manufacturing, Regulations, and Sustainability Are Affecting the Cannabis and Hemp-Based Products Industry,” and “Fast Residual Solvents and Terpenes Analyses in Cannabis and Hemp Products,” co-authored with Jeffery S. Hollis and featured in our January/February 2024 issue.
Dr. Macherone was also a trusted advisor on the educational steering committee for the Cannabis Science Conference. He presented “LC–MS For Regulatory Testing: It’s About Time,” at our Fall 2022 conference and we were fortunate to have highlighted Dr. Macherone in an interview from the conference as well.
We greatly appreciate his contributions to our publications and to advancements in the cannabis industry. He will be missed by many.

Articles
2020
This study highlights a potential concern for the quantitation of acid phytocannabinoids.
A Brief Review of Derivatization Chemistries for the Analysis of Cannabinoids Using GC–MS
This article focuses on the use of GC–MS for the analysis of derivatized cannabinoids in hempseed oil matrix.
2019
A study using LC-qTOF, GCqTOF, and GC–MS/MS to evaluate the selectivity of a model pesticide commonly found in regulatory target lists.
GC-TOF Discovery-Based Profiling of CBD Oil Pet Supplements
In this study, six different brands of CBD oil pet supplements were obtained and untargeted analyses using gas phase-time of flight mass spectrometry were performed.
This review introduces a quantitative polymerase chain reaction (qPCR) assay and compares its performance to culture-based methods.
2018
The liquid chromatography–time-of-flight mass spectrometry (LC–TOF-MS) method presented herein allows for the accurate, precise, and robust speciation, profiling, and quantification of cannabinoids in hemp oil extracts and commercial cannabinoid products for research and development laboratories.
A Comprehensive Approach to Pesticide Residue Analysis in Cannabis
Here we present a straightforward acetonitrile extraction using a solid-phase extraction (SPE) cartridge and targeted dispersive solid-phase extraction (dSPE) cleanup. The final dilute extract is analyzed with both gas chromatography–tandem mass spectrometry (GC–MS/MS) and liquid chromatography–tandem mass spectrometry (LC–MS/MS) for a comprehensive target list (200+ compounds) that encompasses those identified on individual U.S. state lists.
