Cannabinoid Testing

Understanding both cannabinoid content and terpene profiles is essential for crafting effective, consistent, and market-ready cannabis products. Our potency testing uses high-performance liquid chromatography (HPLC) to accurately measure concentrations of major cannabinoids like THC and CBD, as well as minor ones such as CBG, CBN, and CBC. This ensures your flower, edibles, or concentrates are properly labeled, dosed, and compliant with regulations. Complementing this, our terpene analysis uses gas chromatography-mass spectrometry (GC-MS) to identify over 30 aromatic compounds responsible for cannabis's unique scent, flavor, and influence on the entourage effect. Together, these insights help you fine-tune your formulations, deliver reliable consumer experiences, and differentiate your brand in a competitive market.

Contaminant Testing

Ensuring your cannabis products are free from harmful contaminants is essential for consumer safety and regulatory compliance. Our residual solvent testing uses headspace gas chromatography to detect even trace levels of solvents like butane, ethanol, or propane that may remain after the extraction process—protecting your customers from potential toxicity. In addition, we screen for heavy metals such as arsenic, cadmium, lead, and mercury using inductively coupled plasma mass spectrometry (ICP-MS). Because cannabis plants naturally absorb elements from their environment, rigorous metal testing is crucial, particularly for inhalable products. We also perform comprehensive pesticide analysis using both LC-MS/MS and GC-MS/MS to identify even minute traces of chemical residues. These advanced tests ensure your products are safe, clean, and meet the strict standards set by state cannabis regulations.

Microbial Control

For cannabis extracts made using solvents (like butane, ethanol, or propane), residual solvent testing ensures that no harmful chemicals remain in the final product. These compounds, if left behind, can pose serious health risks. Our tests comply with state regulations and use headspace gas chromatography to detect even trace levels of solvents, protecting consumer safety and ensuring compliance.
