Heavy Metals Testing

Metals can be found in soil and fertilizer. As cannabis plants
grow, they take up metals from the soil. ‘Heavy metals’ are
a group of metals considered to be toxic and include lead,
cadmium, arsenic and mercury. Laboratory testing helps to
ensure that your products are free from toxic concentrations
of these hazardous metals. Additional toxic and nutritional
elements are easily added to the analysis list as needed.

There are several ways to determine trace metals in plant
material, all requiring an acid digestion. However, the Inductively
Coupled Plasma Mass Spectrometry (ICP-MS) method provides
the sensitivity to measure low levels of these toxic metals without
the need for additional sample preparation or purchase of
additional expensive sample introduction accessories.
