Gas Chromatography Instruments (GC)
You will need a Gas Chromatograph if you are testing for THC potency, Residual Solvents (metals and pesticides), Cannabinoid Characterization and Terpenes.
Liquid Chromatography Instruments (HPLC)
High Performances Liquid Chomatography (HPLC) will quantify the potency of a Cannabis sample. It’s will also accurately determine the levels of THC, THCA, CBD, CDBA, CBN.
Mass Spectrometry Instruments (MS)
An MS instrument is pivotal when testing for and determining levels of residual solvents such as pesticides, water, butane, carbon dioxide, ethanol and other solvents used in cannabis manufacturing.
Benchtop and Ultra Centrifuges
Centrifuges allow you to separate samples quickly and accurately in order to maximize the effciency of your cannabis operation. This is a perfect instrument for any extraction application.
Cannabis Testing Instruments: Audit-Ready Accuracy for Regulated Labs
The cannabis market is scaling fast, and so are expectations for defensible, standards-based testing. To protect consumers and satisfy regulators, laboratories need validated methods, traceable calibrations, and instrument platforms that produce reproducible results across complex matrices. GMI provides a full suite of certified pre-owned analytical systems that deliver OEM-level performance and documentation at a responsible cost ideal for start-ups and high-throughput labs alike.
What you need to measure and why it matters
A comprehensive panel typically spans:
- Cannabinoids & terpenes: Potency, profile, and label claim verification.
- Residual solvents: Confirmation that extraction artifacts meet limits.
- Pesticides & mycotoxins: Ultra-trace detection for consumer safety.
- Heavy metals: Lead, arsenic, cadmium, mercury screening in plant and finished goods.
- Microbial contamination: Yeast/mold, pathogenic bacteria, and total aerobic counts.
- Moisture/aw: Stability and shelf-life indicators for flower and concentrates.
Instrumentation tailored to cannabis workflows
- HPLC/UPLC (with DAD/UV or FLD): Quantitative cannabinoid potency and, with suitable methods, terpene profiling when GC is not preferred.
- GC-FID / GC-MS(/MS): Terpenes, residual solvents, and volatile impurities; MS/MS for targeted pesticide confirmation.
- LC-MS/MS: Multi-residue pesticide panels and mycotoxins at low-ppb LOQs with matrix effects controlled by internal standards.
- ICP-MS: Heavy-metal screening with collision/reaction cell chemistry for spectral interferences.
- Microbial systems (qPCR or culture-based): Rapid organism detection and enumeration aligned to state requirements.
- Moisture analyzers: Rapid loss-on-drying or halogen methods for process control.
Compliance and data integrity, built in
Regulatory frameworks vary by jurisdiction, but auditors consistently expect:
- Method validation (selectivity, linearity, accuracy, precision, LOD/LOQ, robustness) and system suitability criteria before batch release.
- Traceable calibrations for flows, temperatures, wavelengths/mass axis, and detector response.
- Data integrity controls: CFR Part 11-supportive software, audit trails, user roles, and secure e-records.
- Quality documentation: SOPs, maintenance logs, and change control.
Why choose GMI-Certified instruments
- Verified performance: Each platform is refurbished to original specifications with documented calibrations (flow/gradient, injector precision, wavelength/mass accuracy, baseline noise/drift, vacuum integrity for MS).
- Immediate availability: Avoid OEM backlogs with ready-to-ship, cannabis-configured systems.
- Warranty protection & service plans: Safeguard uptime with access to critical spares and preventive maintenance.
- Capital efficiency: Typical savings up to 50% versus new, enabling investment in standards, consumables, and staffing.
- Top brands configured for your panel: Agilent, Thermo Fisher, PerkinElmer, and others—matched to your state’s analyte list and LOQs.
End-to-end support for faster readiness
- Site planning and installation to meet electrical, HVAC, and venting needs.
- Method transfer assistance (potency, solvents, pesticides, metals, microbes), including matrix-matched calibration and internal-standard strategies.
- Training and SOP templates for routine operation, QC checks, and troubleshooting.Ongoing performance verification with control charts, continuing calibration verification, blanks, spikes, and duplicates.
