To determine the purity and potency of every batch of Hemp cannabis oil each individual extraction is analyzed through a High Pressure Liquid Chromatography (HPLC) system, a Gas Chromatography-Mass Spectrometry (GC-MS) system, and other methods to test for aerobic organisms, yeast, fungus, E. coli, pesticides, heavy toxic metals, cannabinoid potency, and terpenes.
Filtered oil has been through the most processing. Generally, filtered oil has been decarboxylated and then even further refined by filtering out the phytochemicals and plant materials. This makes the oil gold in color which is often considered the highest quality compared to raw or decarboxylated oil. Filtered oil is commonly referred to as “gold” CBD oil and is very popular among consumers. It also tends to be the most expensive, but this isn’t always the case.
