FOREIGN MATTER EXAM
MOISTURE CONTENT
Knowing the moisture content in cannabis products is an essential step to increasing shelf life and preventing mold and other negative health impacts for consumers. If moisture levels are too high, dangerous microbial contaminants can take form.
Testing Method:
Analytical Moisture Balance
When growing, cultivating, and curing raw cannabis materials, it’s important to do so in a clean, controlled, safe environment. Otherwise, foreign contaminants can find their way into your products. Foreign matter such as insects, powdery mildew and other mold hyphae can indicate problematic conditions in a grow or during the handling and processing of retail cannabis. PSI Labs will detect inorganic foreign matter, insects, mold, fungus and mildew infestations as part of our rigorous sample documentation procedure. We’ll also provide you with an attractive, magnified image to use for your internal reports or advertising needs. Despite your best efforts, foreign matter can work its way into your end product. That’s why it’s important to undergo a thorough foreign matter screening.
