Cannabinoid Profiling

Potency testing is used to find out the strength of a base product such as trim, flower, concentrates, or extracts.

Terpene Profiling

Terpenes provide smell and flavor to almost all plants, not just cannabis.

Residual Solvents Screening

When processed incorrectly or incompletely, residual amounts of solvents used during the extraction process can remain in the final material.

Heavy Metals Analysis

Heavy Metals are typically introduced through soil, water, or low-grade fertilizers.

Pesticide Detection

Many pesticides are labeled as organic, and products such as bug bombs, flea and tick treatment, and other common lawn care products utilize pesticides as active ingredients.

Microbial Impurities Analysis

Testing cannabis for microbial contaminants is an important aspect of ensuring the safety of cannabis products.
