Water-free Separations

One of the key issues associated with liquid-liquid extraction (CPC, CCC, LLE) is the use of water and alcohol as one of the polar phases.  Simply put, water is a huge pain to remove from the resulting product.  Due to the fact that water has such a high boiling point and also promotes the production of an emulsified product, water is to be avoided at all costs. Our proprietary methods enable the chromatography paper to completely avoid water in the separation thereby saving time, money, and avoiding a whole lot of hassle.

Chromatography Columns You Can Pack

The columns that we sell can be packed by the customer in less than 10 minutes.The packing material itself is a low-cost compared other proprietary packing materials such as molecularly imprinted polymeric materials.  

Unlike polymeric packing materials, our stationary phase is also mechanically stable so that  the column can be run at high pressure. 

Stationary phase is low cost and can be packed by the customer. The material is also highly mechanically stable so that the column won’t degrade or collapse at high pressure. 

High Yield

 As with any technique, there are always trade-offs between throughput, purity, and selectivity.

Preparative chromatography yields a very high recovery rate compared other competing techniques. For example, it is not uncommon to recover up to 99% of the target cannabinoid. Liquid-liquid techniques typically have much lower recoveries.   

High recovery depends primarily on the selectivity of separation. But it can also depend on the peak shape and operational parameters such as where the chromatographer decides to make the cuts.

Recovery largely depends on what is known in chromatography as selectivity. The greater the separation distance between CBD and THC, the greater the selectivity of the chromatography. 

The separation of THC and CBD is never perfect. In other words, recovery can also depend upon how the operator selects the THC.

 

High Production Output

The throughput is 2-6 kg of broad spectrum hemp extract produced per hour. The production rate depends on many different factors. The great thing about this production rate is that it also includes the solvent recovery time for the eluent that is recoverable by the system. Any solvent left in the sample will need to be recovered separately.

 

Chromatography Methods, Training, SOPs Included

 

 Pure99 equipment comes with built in methods that are selected for the separation of THC and CBD. As a user, you will decide how pure your extract will be and you will also decide on the recovery that you wish to obtain. These selections will impact the overall throughput. You will also decide how many shifts you will have.

Integrated Solvent Recycling

As with any technique that uses solvents, a huge barrier to adoption and use is dealing with all of the solvents that are generated as the technique is scaled up. One of the key benefits of the pure99 is that it automatically recycles and recovers the solvent for reuse. 

Solvent loss can be a key contributor to high operating costs if the solvent becomes entrained with the product, however, this is not the case with the pure99. The pure99 incorporates a falling film solvent recovery system, to avoid the hassle of having to do an extremely large amount of solvent recovery.

What is Chromatography?

extraktLAB has been producing chromatography systems, high pressure liquid chromatography, solid phase extraction, and selective separations materials since 2009. The company was one of the first in the cannabis and hemp industries to implement large scale separations of THC and CBD to produce tailored formulations with targeted THC-CBD ratios.

Chromatography is a separations technique that separates compounds of interest into their individual components. The combined equipment and technique is ubiquitous and is used to obtain pure compounds in nearly every industry that processes fluids.

There are many different kinds of chromatography including gas chromatography, liquid chromatography, and thin layer chromatography. Distinct from liquid-liquid extractions, gas gas or membrane separations, chromatography uses a solid phase or stationary phase and a liquid/gas phase to accomplish the separation.

Why Use Preparative Chromatography?

Preparative chromatography is a technology used to distinguish the various compounds of a mixture and separating them into their pure components.

In the hemp and cannabis extraction industry, it allows manufacturers to distinguish a list of compounds in the cannabis plant and create a specifically formulated product that’s both legal and tailored to the marketplace demands.

It’s also effective at identifying and removing unwanted pesticides, and other residual chemicals. These are essential factors in creating a healthy, safe, desirable product for the end user making supercritical chromatography an essential part of your production.

Scalable Chromatography Solution

The issue of scalability in preparative chromatography goes hand-in-hand with liquid solvent recovery. One of the things which makes traditional flash chromatography a benchtop or lab scale technique is the quantity of liquid that is consumed. This can drive the costs of production to untenable heights.

The pure99 chromatography system solves this liquid consumption in chromatography for a scalable solution.

With integrated closed loop technology, the equipment is designed to automatically recover excess volatile eluent.

Liquid intake is recycled back to the beginning of the chromatography column via built in inert gas counterflow distillation.

The concept of applying a fractional distillation system to chromatography technology enabled the creation of the first scalable chromatography system of its kind in the industry.

Endless Product Formulation Potential

The pure99 supercritical fluid chromatography system is designed to produce broad spectrum oils and purified isolates. This allows producers to keep desired cannabinoids including CBD, CBG, CBN, while removing THC.

This cannot be accomplished with a normal isolation manufacturing procedure. A very specific target removal system is required to perform this kind of specialized product formulation which pure99 is capable of.

Full-Spectrum and Broad Spectrum products have become increasingly valued by consumers in the hemp and cannabis extract market.

Where normally an extraction method would be manipulated to regulate the amount of THC in a final product formulation, pure99 allows for the producer to selectively manipulate quantities of specific terpenes and cannabinoids for specific indications tailored to the consumer’s desires.

 

Frequently Asked Questions

Do you provide SOPs for the Chromatography equipment?

Yes. We provide Standard operating procedures for analytical hplc, preparative hplc, GC headspace, and for sample preparation. We also provide start up kits for each one of these pieces of equipment along with sample management software called the igwLAB

Are the Chromatography Methods Validated for THC removal?

The customer validates the methods according to their company’s validation protocol. Chromatography and cleaning validation protocol for analytical methods are significantly different than production validation protocol and also very significantly from customer to customer.

Do Methods Come with the Pure99?

Yes. We provide the methods for separation of THC and CBD. If the customer desires to separate out other cannabinoids, they are welcome to develop their own methods.

What other Equipment is Required for the Pure99 to Function?

Additional training for HPLC and for headspace GC is typically conducted at our facility in Osceola Wisconsin. On-site training for these items may be purchased by the customer.

Does distillation replace chromatography?

Chromatography and distillation are not analogous. Chromatography utilizes differences in chemical affinity to separate a mixture of components, distillation utilizes differences in boiling points. Wiped film distillation does not separate THC and CBD despite their differences in boiling points. Chromatography will separate THC and CBD into their pure fractions.

How do you remediate THC from CBD oils?

There are several processes for the removal of THC from CBD distillate. These include

1. Precipitation of CBD in a solvent
2. Chromatography separations.
3. Partitioning of THC or CBD different organic solvents.
4. Degradation of THC with oxidation and light.

In the isolate process, the CBD is precipitated from the oil in a nonpolar solvent blend Leaving the THC in the supernatant to be discarded.

The second process is chromatography. In chromatography, THC and CBD are separated again in a solvent while flowing A packed bed of particles. This process can be frustrating for the end-user because it requires a high level of skill to conduct the separation. Oftentimes the particles can fail and plug up if the sample that is being separated has not been properly prepared. If done correctly, this process has the potential to separate out large amounts of CBD from THC.

The third process involves separation by partitioning between two immiscible solvents. This process is very solvent intensive and is costly from the standpoint of solvent usage. There are also issues with solvent contamination of the final broad spectrum CBD oil. If done correctly, this process has the potential to separate out large amounts of CBD from THC.

Finally, the last process involves degrading the THC into CBN with oxidation and uv light. The problem with this approach is that the CBD also degrades so the yield for this process is typically less than desirable.
