Storing and Handling Volatile Residual Solvent Gases in Secondary Containers

The presence of highly flammable hydrocarbons, such as propane and butane, within cannabis concentrates poses a significant safety concern to the end consumer. Laboratory testing of highly volatile gases is complicated by many factors, with the stability and storage of analytical reference standards posing a significant issue. Improper storage of these highly volatile compounds can lead to significant loss of analyte and difficulty in acquiring accurate quantification. The general guidelines in this application note can help extend the shelf life of volatile standards. The exact shelf life of the standards will vary based on usage and should be verified by a lab before use.
