Wondering about the accuracy of an affordable cannabis HPLC analyzer from CTInstruments?
One of the first things we usually get asked is whether our $15,990 cannabis HPLC analyzer is a real HPLC. The answer is yes, absolutely. The second question we typically get is whether it is accurate and how it compares to instruments manufactured by the big HPLC manufacturers + how it compares to tests run by commercial labs.
To answer this, we participated in numerous studies. Below is a table with results from a study done by the National Institute of Science and Technology (NIST), which sent out an NRC hemp certified reference material (hemp sample) to over 140 commercial labs across North America. The CTInstruments HPLC column represents results measured by us using our cannabis HPLC analyzer, compared to the mean value of 140 commercial labs and results measured by the National Institute of Science and Technology.
