In addition to pesticides, the growing conditions for cannabis are also conducive to the growth of molds and fungi which can produce carcinogenic mycotoxins including ochratoxin A and aflatoxins. As a result, testing for the levels of pesticide and mycotoxins in cannabis is important to ensure consumer safety and quality control as these molecules can be highly toxic to all animal organisms and have harmful effects even at very low doses. Contamination can occur in the field, but also during the subsequent phases of transportation, storage, or processing, or when environmental conditions of temperature and humidity are precise enough to develop fungal spores naturally present in the environment.
The use of a universal detector, such as the QSight 220, allows the development of a single analytical method without resorting to a system of derivatization. The MS/MS detector identifies molecules, exploiting the ions generated when subjected to a process of ionization. Each toxin is analyzed in the most appropriate ionization method: ESI + or ESI -.
