  • If your methods are matching the company’s and your results are not then take that up with them. When I worked in QC at a chemical company we had several accounts that set their own specs that were narrower than our own.

    My question would be what are you trying to measure, and what kind of detector are you using? Not every ingredient is going to be picked up by the detector depending on what you’ve chosen.

    If you’re just trying to show your formulation with the ingredient compared to a background without it to illustrate your active ingredient is indeed creating the peak then I would follow the above instructions.
