Based in Minnesota, this independent analytical testing facility has played a pivotal role in shaping cannabis and hemp compliance standards while maintaining a broader scientific footprint rooted in pharmaceutical analysis.
The Origins and Scientific Foundation
The story of chri laboratories is grounded in pharmaceutical science. Unlike many testing facilities that emerged solely in response to cannabis legalisation, this laboratory draws on experience developed within tightly regulated pharmaceutical and medical device environments.
That heritage matters. Pharmaceutical analytical testing demands strict method validation, meticulous documentation and a culture of compliance. These principles became embedded in the operational framework of chri laboratories, shaping everything from sample intake procedures to final certificate reporting.
The laboratory was among the early facilities approved to conduct cannabis testing in Minnesota, positioning it as a foundational contributor to the state’s regulated market infrastructure.
Location and Regulatory Environment
Operating from St Paul, Minnesota, chri laboratories functions within one of the more structured state cannabis frameworks in the United States. Minnesota’s regulatory approach has historically required comprehensive product testing before distribution, particularly for medical cannabis.
This environment demands accuracy, transparency and defensible analytical results. Laboratories must meet stringent accreditation standards, and chri laboratories has aligned its operations accordingly, ensuring compliance not only with state oversight but also with international laboratory standards.
ISO/IEC 17025 Accreditation and Its Significance
A defining feature of chri laboratories is its ISO/IEC 17025 accreditation. For those outside the scientific sector, this credential may sound technical, but it is central to laboratory credibility.
What ISO/IEC 17025 Means
ISO/IEC 17025 is an internationally recognised standard that verifies the competence of testing and calibration laboratories. It evaluates:
- Technical proficiency
- Method validation procedures
- Equipment calibration practices
- Staff qualifications
- Quality management systems
Accreditation under this framework demonstrates that chri laboratories operates under a verified quality management system and produces reliable, reproducible data.
Why Accreditation Matters in Cannabis Testing
Cannabis products are consumed in multiple forms, including oils, edibles and inhalable materials. Inaccurate testing could result in contaminated products reaching patients or consumers. By adhering to ISO standards, chri laboratories reinforces confidence among regulators, producers and end users.
Core Testing Services
The scope of analytical services offered by chri laboratories reflects both regulatory requirements and industry demand.
Potency and Cannabinoid Profiling
One of the most common testing needs involves measuring cannabinoid concentrations, including THC, CBD and other minor cannabinoids. Potency results determine dosage accuracy and labelling compliance.
Using validated chromatographic methods, chri laboratories ensures precise quantification of active compounds. This is particularly critical for medical products, where dosage consistency can affect therapeutic outcomes.
Terpene Analysis
Terpenes contribute to aroma, flavour and potentially therapeutic synergy. Accurate terpene profiling supports product differentiation and consumer transparency.
Through advanced instrumentation, chri laboratories provides detailed terpene breakdowns, helping producers understand product composition at a molecular level.
Heavy Metal Screening
Cannabis plants can absorb heavy metals such as lead, arsenic and cadmium from soil. Exposure to these contaminants poses serious health risks.
Rigorous screening protocols at chri laboratories detect trace levels of heavy metals, ensuring products meet safety thresholds before market release.
Microbial Contamination Testing
Microbial contamination remains a significant risk in botanical products. Testing for moulds, yeasts and pathogenic bacteria is essential.
The microbiological assays performed at chri laboratories are structured to identify contamination quickly and accurately, reducing the likelihood of unsafe product distribution.
Residual Solvent Analysis
Extraction processes sometimes use solvents such as ethanol or hydrocarbons. If not properly purged, residual solvents may remain in final products.
Through gas chromatography and validated analytical methods, chri laboratories screens for residual solvents to ensure compliance with safety standards.
Mycotoxins and Moisture Content
Mycotoxins are toxic compounds produced by certain mould species. Even if microbial counts are low, mycotoxins may persist. Testing for these compounds forms part of a comprehensive safety protocol.
Moisture analysis also plays a key role in product stability and shelf life. By offering both services, chri laboratories supports producers in maintaining quality from cultivation to distribution.
Pharmaceutical-Grade Methodology
What truly differentiates chri laboratories is not merely the range of services offered but the discipline applied in executing them.
Method Validation and Documentation
Every analytical method must be validated for accuracy, precision, specificity and robustness. Rather than relying on generic or loosely applied procedures, chri laboratories implements validated protocols consistent with pharmaceutical standards.
Documentation trails are maintained meticulously, enabling full traceability of results.
Emphasis on Scientific Integrity
In industries where rapid growth can sometimes outpace regulation, scientific integrity becomes paramount. The culture within chri laboratories reflects an emphasis on data accuracy rather than high-volume throughput.
This measured approach builds long-term credibility with regulators and producers alike.
