Analytical Testing Services


The Bureau of Cannabis Control (BCC) has determined the requirements for testing cannabis products. The BCC developed phase-in testing as the industry adjusts for all requirements for compliance. Research and Development services we provide are cannabinoid potency, pesticide, mycotoxin, moisture content/water activity, and microorganism testing services.



Wine and Tannins

Tannins, phenolics, and protein concentrations have important roles in the flavors and astringency of beverages. Winemakers can identify the stage their grapes or wine is by measuring the phenolic profiles such as tannin concentration, epicatechin, and red color. Our consultations provide assistance on winemaking and phenolic profile interpretation.



Veterinary Drugs

Chloramphenicol, Nitrofurans, and Sulfonamides are some of the commonly misused veterinary drugs within the aquaculture industry. The Food and Drug Administration (FDA) requires drug residues in seafood within tolerance level. We offer sensitive LC-MS/MS quantification services for small molecule compounds that can be found in tissue.



Agriculture and Livestock

We provide livestock and agriculture testing and method development services. New additives are becoming more common as the agriculture and livestock industry progress in technology. Betain or veterinary drugs can be tested for concentration levels in livestock feed. We also provide fertilizer, pesticides, or agricultural additive testing for the cannabis cultivation industry.



Glyphosate Testing

Glyphosate is an herbicide that became commercially available for agricultural use in 1974. Application of glyphosate for agricultural industries expanded globally. Recent research about glyphosate toxicity raised controversial discussions about the glyphosate regulations and use.
