When a producer wants to increase the purity of the hemp extract, they often distill it multiple times. We recommend that the hemp extract be distilled twice before it is used for chromatography. After the hemp extract has been distilled, it can be used for chromatography.
Broad Spectrum Hemp Extract
Broad-spectrum hemp oil is an oil derived from hemp that does not contain any detectable amount of THC.
It contains CBD and essential nutrients, which are retained in the extract even after chromatography. This is why many consumers prefer it to crystal or isolate extract.
Techniques for THC Remediation
There are many ways to remove THC from hemp oil. There are four main methods to remove THC from hemp oil: Chromatography, Degradation, Liquid-Liquid Extraction, and Crystallization.
THC can be removed by simply crystallizing CBD. Crystallization will result in the crystallization of CBD. The matrix will effectively remove THC from the CBD isolate.
Some consumers would prefer to retain certain plant characteristics, such as phytonutrients and terpenes that were removed during crystallization, like flavonoids and carotenoids.
A second efficient method to remove THC from oil is to expose it to oxygen and light, which will cause the THC to be converted into CBN.
This makes the oil unsuitable for consumption as it turns into black slime. The THC also undergoes degradation which leads to the degrading of the CBD target molecule.
This technique involves sampling two solvents at once.
If you add herbs or spices to the solvent dressing, the flavors that are soluble will be found in the oil phases. This technique is demonstrated well by oil-vinegar salad dressing. The vinegar phase will contain flavors that are water-soluble.
Centrifugal partition chromatography, a type of liquid-liquid extraction that involves a pumping mechanism, is a method of extracting liquids from the sample. Because it doesn’t have a stationary phase it is more like a liquid-liquid extract than chromatography.
These processes require many passes and multiple extractions. As a result, the cost of these passes goes up.
Chromatography is another method for hemp remediation. It is used extensively in all types of manufacturing industries, including pharmaceutical and food. Because of its versatility and reliability, it has been used to separate complex mixtures.

THC remediation is a costly stage in the hemp extract process. It is important to consider the financial aspects when weighing the operating costs, solvent cost and recovery cost as well as capital equipment.
High-throughput requirements can be addressed by chromatography. However, the cost of calibrating it can be higher than liquid-liquid extraction, crystallization, and degradation.
This is not the case with centrifugal partition or counterflow current chromatography. These processes are expensive to scale up.
The use of heat and light in the degradation of all THC to CBN is not a suitable technique for THC extraction from CBD or hemp gummies extract. This is because the extraction is poor and the extract is very degraded.
Chromatography has an adjustable selectivity, which is defined as the combination of the stationary and mobile phases. You can adjust the selectivity using different techniques.
Efficiency is the fundamental advantage that chromatography has over centrifugal partition and countercurrent chromatography.
Chromatography: The Best Method to Remediate THC
THC remediation can be done in many ways. Because of its high throughput and high recovery, chromatography is the best method for THC remediation.
