Analytical Testing

LEGEND has been perfecting industrial hemp testing since 2015. In doing so, our services reflect the most proactive testing services available to industrial hemp growers and processors.

  • Regulatory testing for THC determined by HPLC/UV
  • Potency testing for hemp-based cannabinoids CBD, CBC, CBDA, CBG, CBN, Δ9‐THC, and Δ9‐THCA determined by HPLC/UV
  • Residual aflatoxins screening measured in parts-per-billion (ppb) determined by UPLC/MS/MS
  • Residual pesticides screening measured in parts-per-million (ppm) determined by LC/TOF/MS or LC/MS/MS
  • Residual solvents screening determined by GC/FID
  • Terpene profile for identifying compounds that make up the final product color and flavor determined by GC/MS
  • Microbiological contamination screening for molds and bacteria
  • Heavy metals testing for Arsenic, Cadmium, Lead, Mercury determined by ICP/OES or ICP/MS (most common metals profile)

HPLC = High Performance Liquid Chromatography
GC = Gas Chromatography
ICP = Inductively Coupled Plasma
MS = Mass Spectrometry
TOF = Time of Flight
UV = Ultra Violet
FID = Flame Ionization Detector
OES = Optical Emission Spectrometry
LC = Liquid Chromatography


In 2015, The Minnesota Industrial Hemp Development Act (IHDA) was passed and it is now law. Minnesota Statutes 18K defined the legal parameters of industrial hemp Hemp sativa L. Under this definition, Hemp sativa L. with a delta-9 tetrahydrocannabinol (THC) content of 0.3% by dry weight or less is legal under the Minnesota IHDA.

In 2016, the Minnesota Industrial Hemp Pilot Program (IHPP) was established by the Minnesota Department of Agriculture (MDA) under the 2014 U.S. Farm Bill (Public Law 113-79). Since then, program participants have been growing and processing industrial hemp to meet the MDA’s research goals.
