Tackle Emerging Cannabis Regulations with Confidence

Residual pesticide analysis in cannabis matrices is arguably the most challenging of all the mandated regulatory assays due to the complexity of the matrix and the very low action limits.

Further complicating the issue is the inclusion of pesticides not amenable to electrospray ionization (ESI), the most common LC/MS/MS ionization source for this analysis.

This Application Brief demonstrates:

• The correct ionization mechanism for pentachloronitrobenzene (PCNB)
  using Ni-APCI LC time-of-flight mass spectrometry (Ni-APCI LC/Q-TOF)
• Evaluates the appropriateness of this analytical technique for this analyte
