Cannabinoid Tests

We are a DEA registered facility (RA0292603).  We report THC as a limit test unless the client has listed their specification as “not detected”:

  • THC amounts >0.3% are reported as “Presence Detected”
  • THC amounts detected at <0.3% are quantified in the report
  • Customer specific reporting protocol for THC is available upon request

This method was developed and validated in accordance with current ICH guidelines. Here is a summary of the validation results for various matrices

  • Accuracy: CBD and THC recovery ranges are 80-125%, at three spike levels
  • Precision (Repeatability): %RSD for peak area <4% CBD, <7% THC
  • Specificity: Verified with spectral purity by photodiode array
  • Detection Limit (LOD): CBD = 0.023%, THC = 0.022%
  • Quantitation Limit (LOQ): CBD = 0.076%, THC = 0.074%
  • Linearity: Correlation coefficient (R2) > 0.999, determined by five-point calibration curve

This method is suitable for common sample matrices such as crude material, oils, liquid extracts, and powdered extracts. Finished product formulations may require method development.
