Analytical Testing and Analysis of Residual Solvents

Residual Solvents are Chemicals and solvents used in the extraction process and are notorious for their carcinogenic properties, therefore it is important to know how much of these chemicals and solvents still remain in the products once the extraction process is complete. They can be tested as individual components or as a finished product. Residual Solvents are organic volatile chemicals and are separated into three classes: Class 1 residual solvents are highly toxic. Class 2 residual solvents are considered moderately toxic and Class 3 residual solvents are the least toxic. To determine the quality and safety levels of the chemicals used in production of cannabis concentrates. HS-GC-MS method is used to analyze cannabis products to determine what trace residues are present.
