Looking for some general comments/ opinions for my proposed cannabis detection (basic standards to begin with moving to biological samples and actual plant material when optimized). I do not have access to LC-MS.
- Potency of THC total and CBD total to be done by GC-FID
- Residual Solvent Analysis: HS-GC
- Pesticides: GC-MS/ GC-MS/MS
- Samples will be prepared using QuEChERS and SPE clean up
I have experience of quantitating THC in biological samples using GC-MS but found recovery to be variable and not consistent (because of poor SPE technique) with results often being 'present'.
