Pesticide Analysis FAQs with Julie Kowalski, Cannabis and Hemp Testing Consultant
August 19, 2020 @ 3:00 pm - 4:00 pm
Trace level analysis like pesticide residue testing comes with specific challenges and performing this analysis in cannabis can be a frustrating experience. Establishing a robust method can help mitigate long term problems but method criteria and performance parameters can be difficult to choose without the benefit of consensus methods and a long history of detailed published methods. It can be hard to know where to start with method fundamentals and how to experimentally determine performance. Luckily, the chemical contaminants community has developed excellent practices that can be used. It is important to understand fundamental criteria and options for determining performance because these directly impact the quality of testing and ability to meet regulatory requirements.I often help people with pesticide testing in cannabis and will discuss some of the most important method criteria and performance experiments needed when establishing a pesticide method in your lab. This presentation will answer these common questions.
