Often overlooked but critical to most cannabis laboratory operations is sample workflow and sample preparation, having these areas figured out early in the start-up process is essential – particularly in the prevention of sample cross-contamination.

The primary focus of this presentation is to discuss sample workflow with an overview of sample intake and processing. Once the sample is accepted at the laboratory – how does it move from one test (or station) to another and what considerations are there to prevent cross-contamination of the sample?  Are there any special storage requirements, retain procedures, and overall best sample-handling practices?

Considerations will be made regarding sampling and sample size(s) which based on the regulatory jurisdiction are typically different, as well as the sample test portion size.
Problem areas for contamination and how to prevent further contamination-possible test fails will also be briefly discussed. 

Learning Objectives:

1. Discuss sample Workflow and Sample Intake/Processing best practices.

2. Discuss sample contamination prevention.
