High performance liquid chromatography is an essential function in any hemp and cannabis extraction businesses. There are a number of HPLC applications within the extraction market capable of streamlining and upscaling any cannabinoid product line. In this article we discuss chromatography uses, applications and the pure99 system.
What is HPLC Chromatography?
Very simply, chromatography is a technology used to separate the various compounds of a solution. In hemp and cannabis industries, it allows producers to separate a list of compounds in the cannabis plant to allow for a specifically formulated product that is both legal and tailored to the market demands. It is also capable of identifying and removing unwanted pesticides, and other residual chemicals. Let’s get into the details of HPLC applications and Pure99 with R&D Chemical Engineer, Aaron Iwen.
What is Pure99?
So, Pure99 is HPLC chromatography for the hemp and cannabis producer, but what exactly does that mean? What benefits would a manufacturer have by using this in their own extraction business? “Pure99 is a scaled chromatography system designed to separate cannabinoids of particular interests,” Iwen says. “It’s a liquid chromatography system. What’s great about this is that a manufacturer would be able to use a combination of solvents in order to achieve a target separation. One of the things that is unique about a liquid system is that you have a certain amount of liquid consumption.”
No scalable solution… until now.
FDA regulations make pure99 essential
The hemp and CBD industry has a strict set of regulations according to the jurisdiction of any particular country. For example, The United States’ FDA regulations on CBD products requires that a product contain no more than 0.3% w/w THC. The problem with this is that hemp cultivators may have issues growing a crop that truly contains less than 0.3% of THC. Thus, if a CBD product is made from biomass that contains more THC than is federally approved, it cannot be sold as it would be a technically illegal product. So, what then? The answer lies in chromatography. “Until that 0.3% THC threshold is lifted by the FDA regulations, you almost certainly will have to take out a number of THC from your final product in order to make it legal. We can do that with this technology and reliably do it. And, when we do this, we can still maintain the rest of the plant profile and selectively remove THC from it.” “Some strains of the plant just don’t meet that threshold. If you do have a strain that is below the 0.3% threshold, then you wouldn’t need this technology, but biology is always changing, so it’s anyone’s guess. Any particular strain that you put in the ground isn’t necessarily guaranteed to have no THC in your plant. So having this technology that is capable of removing it when it is above the threshold”
Particular HPLC Applications: Pesticides, Chemicals, Cannabinoids and Terpenes.
“There are an infinite number of variables in biology that could affect your plant, so you’re not going to be able to get around regulations just by the selection of a plant. There are people that want full spectrum products where the cannabinoid profile is unedited.” “That’s great if you have the plant that can give you that, but it has to maintain the legal regulation; the bottom line is that many plants don’t have that. You can’t even predict it. You can make every effort to have minimal THC in your biomass, but different variables are going to cause different products to be created. That could mean more THC even in a strain that you specifically selected to have zero THC.” “And, while most of this technology is geared towards cannabinoid separation and removal, you could potentially remove unwanted pesticides from a final product if it is tuned to a specific target.”
The Reality: Chromatography Will Always be Necessary
Even if the FDA removes the less than 0.3% THC regulation, there will still be customers on the ground floor and producers that will desire a product that is thc free. This means that chromatography will always be an essential part of the hemp and cannabis product formulation process. Chromatography uses will always be necessary. Not only is it legally necessary while certain regulations on THC are in place, there will also always be customers that are looking for a CBD product that has zero THC. You’re never going to be able to get around it.
