How to Prepare calibration standards for CBD testing

If you want accurate CBD potency results, calibration standards are essential. Without them, you can’t be sure your instrument is reporting the right concentrations or that your batches are consistent.

In this video, we walk through the full process of preparing a series of CBD calibration standards, from the first stock solution to the final dilution. Everything is shown step by step so you can follow along with confidence, whether you’re new to the lab or refining your workflow.

Here’s what we cover:
* The equipment and consumables you’ll need: vials, pipettes, methanol, analytical CBD standard, PPE.
* How to safely handle and open the analytical standard ampoule.
* Preparing the 1.00 mg/mL stock solution and transferring it correctly.
* Making accurate dilutions for 0.50, 0.10, 0.05, and 0.01 mg/mL standards.
* Good pipetting practice, including positive displacement pipettes and avoiding cross-contamination.
* Why thorough mixing and proper labelling are critical for reliable results.
* How the complete set of standards is used to build a calibration curve on the GC.

By the end, you’ll understand not just how to make the dilutions, but why each step matters, and how reliable calibration underpins every accurate potency test.
