Process of Testing CBD in a 3rd Party Lab

It is important when testing your products as a consumer or a wholesaler when buying CBD to find an accredited lab and get a reliable COA (certificate of analysis).

Residual Solvent Analysis

Residual solvent analysis involves the extraction of active ingredients from hemp or cannabis via the use of solvents such as ethanol, carbon dioxide, butane, water, and other materials. Solvents play a significant role, with large volumes required in order to achieve higher purity levels and increase the efficiency of extraction.  Following extraction, further testing must be done to ensure that the highest percentage possible of solvents has been removed. Following this, the amount of residual solvent left in processed cannabis, expressed in parts per million (ppm), can be determined. Headspace analysis is performed to determine the amount of residual solvent present. This involves the use of a gas-tight syringe to obtain a small gas sample from those in the headspace of a sealed vial of the prepared sample.

Heavy Metals

Cannabinoids collects heavy metals. It absorbs them from the soil, water and air. The plant is an excellent bioremediator, soaking up a large majority of whatever the roots come in contact with. Even at extremely low levels, heavy metals such as lead and cadmium can be extremely hazardous to one’s health. Without uniform regulations for heavy metal testing, patients have no way of knowing whether their products are laced with cadmium, lead, arsenic or mercury – all of which pose serious health risks. This test can detect heavy metals at concentrations as low as one part per billion, giving patients and their caregivers an accurate profile.

Potency Analysis

The potency analysis refers to the percentage of cannabinoids contained in the sample being tested. Depending on the state in which testing occurs, a sample’s THC and CBD levels, along with its tetrahydrocannabinolic and cannabidolic acids may be all that’s required. Other labs may opt to test samples for their CBC and CBG as well. Testing for potency involves gas or liquid chromatography for a range of matrices.

Terpene Analysis

The measurement of fragrance and flavor compounds present in a cannabis sample requires terpene analysis. Gas and liquid chromatography is used to determine terpene content, which contributes to the sample’s flavor profile.

Testing Lab Setup and Educational Requirements

There are several tools and procedures required for the purpose of cannabis testing. When a sample is submitted to the lab for potency testing, it will typically undergo an initial visual inspection with a high-magnification dissecting microscope. This will reveal the presence of any mold or visible contaminants.  Several tasks are involved with the processing of cannabinoid for medicinal usage. Therefore, a wide range of degrees, knowledge, and experience is required.


It’s important to know about the third party lab you are taking your material to for testing. Make sure they are accredited and test for all solvents not just some. The result is keeping customers happy knowing that they can rely on you and your product, do your homework. Make sure your getting what you want and quality CBD.

Get Educated On CBD

It has been quite the media buzz that CBD has gained in such a short time. A few years ago, no one even knew what CBD was. It’s become so popular and such a hot new product in market that everyone wants to know more about it. These days we can find CBD at gas stations, CVS, grocery stores and many other mainstream retailers.

The most important part to this is really understanding and educating yourself about CBD and its benefits.

CBD has become very socially acceptable and no wonder that companies large and small all are wondering how they can come out with the next best product with CBD and if not they are more than likely invested into research stages.

First of all not all CBD products are created equally. Much the same when your researching the best protein powder or perhaps your looking for a new lawyer to represent you. You must do your research and understand before making decisions. In this case it’s about optimum wellness to understand how it can support your system. Well the first step is to have a firm understanding of the endo-cannabinoid system and the potential benefits of hemp extract, you can then begin to comprehend the difference in products.

First, we’ll start with the source of CBD oils. The most common source for CBD oil is hemp. Hemp naturally has a low quantity of THC — for it to be classified as hemp in the United States, the plant must have a THC concentration of 0.3% or less. This low concentration of THC makes premium grade CBD oil a more family-friendly option. However, just because the CBD oil is derived from hemp doesn’t mean it’s of superior quality.

Quality comes from the beginning, here are a few things you should know.

1. What seeds were used?
● Find out where the seeds were grown to make the CBD oil and what types of seeds did they use when farming the hemp. Things like a seed to sale tracking can be requested. This would provide a map for companies to give quality assurance on what they are selling.

2. Where was it grown and what was their cultivation procedures?
● Farmers have different methods of farming the hemp. Not all manufacturers have farms like us at CNP Operating. Many manufacturers purchase hemp biomass and run it through their extraction method. Its important to know cultivating ways, is the farm organic or is there additives? We at CNP are organic hemp farmers.

3. What extraction method is used?
● There are different ways of extraction. Some of the most common are Co2, Ethanol or Butane. At CNP we use Ethanol as it is reusable and green energy and we get the cleanest product results. Some companies use chemical solvents such as hexane. This compound will speed the extraction process up and, in some cases, produce a higher yield of oil. However, it also introduces a foreign chemical into the process. Some chemical solvents may have reactions with the compounds in the hemp extract. While it may or may not diminish the potential benefits, it does tarnish nature’s intended support.

4. Third party testing results
● CBD is still going through regulations, so you need to do your research. many companies us at CNP Operating make sure to be transparent about their products. We test in-house at our lab and send it to third party testing for all batches made. Its crucial to get third party lab reports that test for everything not just a few solvents, they should test for every solvent and potency levels. If the product does not test and pass we won’t sell it.

Our purpose is passion. We are passionate about proving quality product, that support a healthy lifestyle. Before you go and buy a product or work with a manufacturer, make sure you do your research and read up about the company. If you can find lab results from them ask. We at CNP operating are proud to show this sort of transparency and information with you!
