Why pure99 for Chromatography?


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. The issue with this is water is very tedious to remove from the end product being extracted. Because water has a very 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.

High Production Output

The throughput of our chromatography systems depends on the column. Our largest column is 13L and will produce multiple kg of broad spectrum hemp extract per hour. The production rate depends on many different factors and your column, your method, and your sample will determine the ultimate throughput.  And the throughput will vary depending on your goals.   The great thing about the pure99 is that production rate also includes the solvent recovery time for the eluent that is recoverable by the chromatography system. Any solvent left in the sample will need to be recovered separately.

Packable Chromatography Columns

The chromatography columns 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.

Chromatography Methods, Training, SOPs Included

extraktLAB’s pure99 chromatography equipment comes with built in methods selected for the separation of cannabinoids. As a user and researcher, you will decide how pure your extract will be and you will also decide on the recovery that you wish to obtain with this chromatography equipment. These selections and components will impact the overall throughput. You will also decide how many shifts you will have.

Integrated Solvent Recycling

As with any chromatography technique that uses solvents, a huge barrier to adoption and use is dealing with all of the solvent generated as the technique is scaled up. One of the key benefits of the pure99 chromatography system 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 during the chromatography process, however, this is not the case with the pure99. The pure99 chromatography system incorporates a falling film solvent recovery system, to avoid the hassle of having to do an extremely large amount of solvent recovery.


High Yield

As with any chromatography method, there are always trade-offs between throughput, purity, and selectivity. Preparative chromatography yields a very high recovery rate compared other competing chromatography techniques. For example, it is not uncommon to recover up to 99% of the target cannabinoid. Liquid-liquid techniques typically have much lower recoveries.

But this 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 cannabinoids, the greater the selectivity of the chromatography. The separation of cannabinoids through chromatography is never perfect. In other words, recovery can also depend upon how the chromatography operator selects the psychoactive cannabinoid.

High recovery during chromatography depends primarily on the selectivity of separation.

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 extraction and hemp industries to implement large scale chromatography separations of cannabinoids to produce tailored formulations with targeted cannabinoid ratios.

Chromatography is a separations technique that separates compounds of interest into their individual components. The combined chromatography 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, column 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.

Chromatography Explained

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

Chromatography is 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 High-Pressure Liquid 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 machine solves this liquid consumption in chromatography for a scalable solution. With integrated closed loop technology, this chromatography 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.


Why Use Endless Product Formulation Potential Chromatography?

Preparative chromatography is a technology used to distinguish the various compoundsThe pure99 High-Pressure Liquid Chromatography (HPLC) system is designed to produce broad spectrum oils and purified isolates. This allows producers to keep desired cannabinoids including CBD, CBG, CBN, while removing psychoactive cannabinoids during the chromatography process. of a mixture and separating them into their pure components.

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

Full-Spectrum and Broad Spectrum products have become increasingly valued by consumers in the hemp and botanical extract market, and chromatography is one of the best methods to ensure quality full and broad spectrum products.

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