Instrumentation Used

We perform our pesticide screening on Agilent Technologies’ Inductively Coupled Plasma mass spectrometry (ICP/MS). We invested in the right instrumentation to accurately quantitate the detection limits set by the MED and CDPHE.

Having the right equipment is critical, but it is only one piece of the Agricor Validated Laboratory System. Our lab is the ONLY cannabis testing facility set to the same standards of a Pharmaceutical Laboratory. By following Good Laboratory Practices (GLP) we deliver the most accurate results in the industry.
