Icp Ms Testing

ICP-MS (Inductively Coupled Plasma Mass Spectrometry) is an analytical technique used to measure trace elements and heavy metals in cannabis plant material and final products. This laboratory method ionizes sample atoms and sorts them by mass-to-charge ratio, allowing detection of contaminants like lead, cadmium, arsenic, and mercury at parts-per-billion (ppb) levels. ICP-MS testing has become standard in regulated cannabis markets to ensure compliance with safety thresholds established by regulatory bodies. The technique's sensitivity makes it particularly valuable for identifying bioaccumulation of soil contaminants in cannabis crops. Understanding ICP-MS results helps breeders and cultivators select genetics and growing practices that minimize heavy metal uptake.

Breeders use ICP-MS data to identify plant lines with naturally lower heavy metal accumulation rates, informing parent selection for cleaner cultivars. Comparing ICP-MS results across related genetics helps establish which lineages are more resilient to heavy metal stress or exclusion.
