Heavy Metals

Heavy metals can be found in soil, water supply and in many nutrients used by industry participants. Cannabis is prone to absorbing heavy metals and can cause metals to bioaccumulate in the plant structure.
 
Highgrade Labs heavy metals screening helps to ensure metal presence is below limits considered for safe consumption.

Heavy metals testing is performed on a 7800 ICP-MS from Agilent. This instrument creates plasma (the fourth state of matter) by circulating, heating, and igniting argon gas in a vacuum.

All samples are prepared and extracted using acid-assisted microwave digestion, on a Milestone Ethos Up, to dissolve the sample before being placed on the ICP-MS.
