Residual solvents

 

Laboratory provides a concentration of the following residual solvents: Butanes, Heptanes, Benzene, Toluene, Pentane, Hexane, and Total Xylenes. If there are applicable regulatory concentrations the Laboratory certifies against the listed value.  If requested the Laboratory will provide limits of detection and quantification.

 

The method uses a Heads Space Sample Loop coupled with a gas chromatograph and mass spectrometry to identify and quantitate the target analytes. 

Hemp and medical cannabis consumers are increasingly opting for potent concentrates such as butter, hash oil, shatter, wax, etc. To make these products, cannabinoids and terpenes are often isolated from the flowers (or buds) and other plant materials using a solvent-based extraction process. This process usually begins with a solvent wash and extraction, winterization, isolation, and clean-up. In the clean-up phase, solvents (CO2, ethanol, or other hydrocarbons) are then eliminated from the concentrate using such methods as heat or pressure. This removal process is critical as all of these solvents pose health risks for consumers.

 

Test Duration: 1-3 days

MedCan Lab will test for the 14 most commonly used extraction solvents, including: 

 

  • Benzene**   

  • Chloroform

  • Acetone

  • Acetonitrile

  • Butane

  • Ethanol

  • Heptane  

  • Hexane** 

  • Isopropyl alcohol  

  • Methanol  

  • Pentane  

  • Propane  

  • Toluene**  

  • Total xylenes (o-, m-, p-) 

** Contaminants in solvents
