Cannabis and Hemp Testing Solutions

Pesticides

Testing cannabis for pesticides is an important step in ensuring product safety and quality. The number of regulated pesticides that are required to be monitored varies by state, as do the action limits which range from 0.01 µg/g (10 ppb) to above 1 µg/g (1 ppm). Waters robust and rapid method for monitoring pesticides delivers results below the current guidelines so that you are compliant today and in the future.

Recommended Products: 

Xevo TQ-S micro LC-MS/MS 
For accurate analysis of most pesticides

Xevo TQ-GC GC-MS/MS 
For pesticides that require a harder ionization technique

Key benefits

• Simple extraction and dispersive SPE (dSPE) clean up procedure

Mycotoxins

Mycotoxins are a group of naturally occuring chemicals produced by certain moulds which can grow on crops produced, transported or stored in humid and warm conditions.  Mycotoxins, and in particular aflatoxins (G2, G1, B2 and B1) and Ochratoxin A, can cause a variety of adverse health effects. Waters offers a range of options for monitoring mycotoxin levels from simple, easy to use strip tests to confirmatory analysis using LC-MS/MS.

Potency

Cannabis sativa is a complex natural product that is known to produce at least 100 different cannabinoids. Traditionally, laboratories have focused their analysis on five core compounds that the strength of any cannabis product is measured by: d9-THC, THC-A, CBD-A, CBD, and CBN. 

Recently, more attention has been paid to some of the other minor cannabinoids, which requires methods that are capable of higher resolution separations. High Performance Liquid Chromatography (HPLC) and Ultra Performance LC are ideal for potency determination as they can identify and measure structurally similar cannabinoids and their different forms (e.g. free form and corresponding acid forms of THC and CBD) in a single analysis.
