Trace Solvents



Consumer safety is our number one concern , this is why residual solvent testing is used to ensure that the cannabis products are safe to consumer.  Cannabis flower extraction of cannabinoids and terpenes is a very common method these days, so the need for residual solvent testings has arisen. Since many of extraction processes use some kind of solvent that can be potentially dangerous for consumption extracts should be tested for residual solvents.  This type of testing is mandated and is seen in all major consumer products from medicine to candy.


We currently offer a standard test for 30 organic solvents:


  • 1,4-Dioxane
  • 2-Butanol
  • 2-Ethoxyethanol
  • 2-Propanol
  • Acetone
  • Acetonitrile
  • Benzene
  • Cumene
  • Cyclohexane
  • Dichloromethane
  • Ethanol
  • Ethyl Acetate
  • Ethyl Ether
  • Ethylene Glycol
  • Heptane
  • n-Hexane
  • 2-Methylpentane
  • 3-Methylpentane
  • 2,2-Dimethylbutane
  • 2,3-Dimethylbutane
  • Isopropyl Acetate
  • Methanol
  • n-Pentane
  • iso-Pentane
  • Tetrahydrofuran
  • Toluene
  • o-Xylene
  • m-Xylene
  • p-Xylene
  • Ethyl Benzene


For a premium test we will also quantitate 5 common gases.


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


If there other solvents you wish to be tested that are not on either list please contact us and we can start a custom analysis for you today.


Currently there is not list a standard list or acceptable concentrations for California but as soon as it becomes available we will start testing for those regulations.  We will provide you with the quantitative results which can be compared to acceptable concentrations that are provided from Oregon State for their mandatory cannabis testing.


We use a GC-FID method to quantify residual solvents, we need 1  g of sample for the test.
