Test Benefits

At Encore Labs, we employ a sensitive HS-GC/MS method to determine which trace solvents are present and if they pass state requirements.

What We Test For

Regulation

Residual Solvents and Processing Chemicals Testing

  1. The laboratory analyzes a portion of the representative sample of manufactured cannabis product or pre-rolls to determine whether residual solvents or processing chemicals are present.

  2. The laboratory shall report the result of the residual solvents and processing chemicals testing in unit micrograms per gram (μg/g) and indicate “pass” or “fail” on the COA.

  3. Solvents tested include Acetone, Benzene, Butanes, Ethanol, Heptane, Hexanes, Methanol, Pentanes, Isopropanol, Propane, Toluene, and Xylenes.

  4. The sample is considered passing testing if the presence of any residual solvent or processing chemical is below established limits.

  5. If a sample fails residual solvents and processing chemicals testing, the batch from which the sample was collected fails residual solvents and processing chemicals testing and shall not be released for retail sale.
