Cannabis HPLC Analyzer Accuracy
We take the accuracy of our cannabis HPLC analyzer, validation of test methods, and sampling protocols extremely seriously. With our instrument, you will be operating like a certified professional lab. In fact, we have a comparison study of our results to other ca. 140 labs in North America available on request.
Detection limit of most cannabinoids is 0.03ug/mL (30ppb, 0.000003%)
Below are results of measuring a typical hemp sample, followed by an image of stacked 3 consecutive measurements. There are two observations from this measurement:
The retention times are consistent and repeatable, giving the confidence in the ability to correctly identify the correct cannabinoids.
The measured concentrations are very repeatable as indicated by height/area of each peak. The calculated relative standard deviation (RSD) in this case ranges from 1.19% to 1.70%, while for cannabinoids with very low concentrations manifested as very small peaks (in this sample CBN, d9-THC, and d9-THCA) the calculated RSD ranges from 4.62% to 5.63%. In case of need to further refine the latter 3 compounds and improve both accuracy and RSD, the sample would simply be less diluted resulting in higher peaks for these 3 compounds.
