Microbiological Contaminants & Mycotoxin Screenings

What's Potency Testing?

Plant matter, including marijuana, are ideal breeding grounds of many types of bacteria and molds.  Many of the mold species are capable of creating compounds that are known for causing certain diseases and cancers-mycotoxins.  Patients that are experiencing immune system impairments are at high risk from mycotoxin contaminated products. 

The major groups of mycotoxins include: Aflatoxins, Ochratoxin, Citrinin, Ergot, Patulin and Fusarim. Aflatoxin B1, aflatoxin B2, aflatoxin G1, aflatoxin G2 and ochratoxin A are the most commonly regulated. Check with your state for which mycotoxins are required to be tested and what their maximum permitted levels are.

Liquid chromatography is used to measure mycotoxins. Depending on the application and detection level needed a laboratory could use LCMS, Triple-Quadropole MS (LC-MS/MS) or an HPLC instruments.

Liquid Chromatography Mass Spectrometry

LCMS Mycotoxin Testing

An LCMS is one instrument that can be used to test for contaminates in cannabis samples. With the addition of an HPLC as a front end for sample introduction greatly improves speed and through put.

Triple Quadropole Mass Spectrometry

GC Potency Testing

Mycotoxin & contaminant testing are regularly performed using Triple Quadropole Mass Specs. Often coupled with an HPLC, a Triple Quad MS can be an excellent choice for laboratories looking to identify and quantify mycotoxins.

High Pressure Liquid Chromatography

GC Potency Testing

Another common way to measure contaminants such as mycotoxins is to employ a High Pressure Liquid Chromatography system. The HPLC detector used is a Fluorescence Detector (FLD) and a Post Column Reactor. Some applications have also called for the HPLC to be coupled with a ultraviolet (UV) or diode/photodiode array (DAD/PDA) detectors.
