Food and Cannabis Elemental Analysis Part 2: Elemental Sample Prep for the Food and Agriculture Lab – Optimizing Your System for High Matrix Samples

Trace elemental analysis of foods and cannabis products is essential to ensure that products are suitable for consumption. The analysis of minerals and additional trace elements is also important because it provides labelling information that is required when these products are used as nutritional.

Agilent has presented a webinar series that focuses on elemental sample preparation to optimise high matrix samples in the food and agriculture testing space.


Part 1

We will cover the entire Agilent elemental portfolio. Each of the different instruments’ strengths and how they meet the challenges that food and cannabis labs have.


Part 2

We will focus on preparing your samples, including microwave digestion. We will also cover how to optimize your system for high matrix samples and a diverse sample set.


Part 3

We will put it all together, with running samples live in the lab. We will also share additional tips and tricks for obtaining excellent analytical results in these difficult matrices.

This focused information on spectroscopy applications is valuable for the emerging cannabis market as well as analysts who are seeking to master skills for food testing.

Mark Kelinske is an Applications Chemist with Agilent Technologies, specializing in advanced ICP-MS and ICP-MS/MS techniques. He received his undergraduate and graduate degrees from Texas A&M University in College Station, TX. Prior to Agilent, Mark was a senior research scientist and research group manager with Southern Research Institute in Birmingham, AL, where he focused on low-level analytical chemistry, method development, and research program management.


Chris Conklin
Atomic Spectroscopy Product Specialist
Agilent Technologies, Inc.

With a degree from the University of Wisconsin – Eau Claire, Chris worked in, and lead, a quality control lab testing fine chemicals ranging from reagent grade to high purity. Over the course of 12 years in that role, Chris has run a variety of atomic elemental instruments and techniques including AA, ICP-OES, and ICP-MS. As a result, he has seen most of the periodic table in its elemental form and overcome the associated interferences. In 2018, Chris brought that knowledge and experience to his current role with Agilent as the Product Specialist for Atomic Spectroscopy supporting AA, MP-AES, and ICP-OES for the Eastern US.
