Solvents can be used in the production/extraction of cannabis derivative products such as oils, distillates and other types of concentrates.  Residual solvents can be unintentionally left behind in the end product and cause harm to consumers. 

OA utilizes Gas Chromatography - Mass Spectrometry (GC-MS), along with Headspace Autosampling to quantify residual solvents in manufactured cannabis products to ensure those products are free from solvents or contain less than a specified limit. We are able to test for numerous volatile compounds, including the following solvents: acetone, butane, ethanol, isobutane, isopropanol, methane, propane, pentane, and hexane.
