Do you prepare terpene samples alone or use the potency extractant?

So I have seen labs do it both ways.

  1. Prepare the sample for potency testing and then use the extractant for both Terpenes and Potency. This saves time and money but has some drawbacks.

  2. Prepare the sample for terpenes testing only. Which requires more sample from the client but can allow for more targeted preparation techniques and internal standards etc.

I am not sure what the best plan of approach here is but I would really love to efficiency boost that process #1 provides.
