Oregon-Specific Cannabis Residual Solvents Mix #1

A ready-to-go, easy-to-use mix of solvents specially formulated for labs performing cannabis residual solvents analysis with the challenging Oregon solvents list. This is one of a two-part mix designed for use with both the FET and dilution methods of sample introduction, and is formulated in n,n-dimethylacetamide, which does not freeze like DMSO, enhancing usability and stability. Analyte ratios are formulated to correspond to ratios in the Oregon solvent list wherever possible.

This standard contains the volatile solvents that are gases at room temperature and is designed to be single-use only, since the concentration of gases like propane, isobutane, and butane cannot be maintained under storage after the ampule has been cracked. For more information on the handling of gas standards, read our Directions for Gas Standard Handling.
