Residual Solvent Testing

 

There are dozens of different types of cannabis products, and a number of them require using some type of processing solvent during production. In general, the processing chemicals used to make most cannabis products are harmful when ingested or inhaled. Residual Solvent screening is the only way to ensure that these products are safe for consumption. This type of testing is mandated by the California Bureau of Cannabis Control and is used in all major consumer product industries, ranging from medicine to candy.

 

How We Test for Residual Solvents

 

We use a Gas Chromatography- Flame Ionization Detector to quantify the 18 residual solvents listed in the BCC Regulations (pg. 117) for compliance.

Solvents We Test For:

  • benzene
  • chloroform
  • dichloroethane
  • hexane
  • trichloroethylene
  • acetone
  • acetonitrile
  • butane
  • ethanol
  • ethyl ether
  • ethyl acetate
  • heptane
  • isopropanol
  • methanol
  • DCM
  • pentane
  • toluene
  • xylenes

 

For A Premium Test We Can Quantify 5 Common Gasses:

 

  • n-Butane
  • Isobutane
  • Ethylene oxide
  • Propane
  • neo-Pentane

If there are other solvents you'd like to test for that are not included in the standard Residual Solvents test, please contact us about conducting a custom analysis to meet your needs.

 

All R&D results are unofficial. For information on certified testing please call the lab at (858) 623-2740.

We currently follow activity levels based on the 2018 California Cannabis Regulations. To view these, visit our 2018 CA Testing Regulations page.

Currently we have five testing focuses: potency, terpenes, residual solvents, microbials, and pesticides, but are willing to look into new categories that arise. Our goal is to raise the cannabis testing standards to a level at which the cannabis community can trust...

Because pesticides are used in the cultivation of cannabis, they need to be tested for in flower, trim, and extracts. When flower or trim is extracted for cannabinoids and terpenes, the pesticides are extracted and concentrated as well. When this happens it leads to...

Terpenes are naturally occurring small organic molecules that are produced from plants. Terpenes are what makes plants smell a certain way, which is then extracted and sold as essential oils. In cannabis over 100 terpenes have been detected which give them their unique smell and taste...
