What is Plasma?

Plasma is often referred to as the fourth state of matter—an energized gas made up of ions, electrons, and neutral particles. It is created when gas molecules are ionized, producing a dynamic environment full of reactive species.

Why are we using Low-Pressure Cold Plasma?

Different plasma types are tailored to specific technical applications, but cannabis has unique requirements: effective treatment must deliver high, uniform decontamination while preserving critical secondary metabolites such as cannabinoids and terpenes.

At GOC Nexus we operate under low-pressure cold plasma conditions to meet these demands. Low pressure minimizes process-gas consumption and keeps treatment temperatures cool, protecting the delicate structure and quality of the flower.

The vacuum additionally produces a gentle drying effect that supports the transition from GACP-compliant raw material to an EU-GMP certified medicinal product.

By avoiding ozone formation and instead generating reactive oxygen species (ROS) inside the plasma, we achieve full, uniform decontamination throughout the chamber. Cold plasma—produced at low temperatures and low pressures—offers a cutting-edge solution for safe, effective and residue-free microbiological control.

Why is Cold Plasma not a traditional chemical treatment?

Our technology uses pure oxygen to generate short-lived reactive species (10^-6 – 10^-10 s). These radicals quickly neutralize contaminants and then recombine into harmless, stable compounds, leaving no residues once the product returns to atmospheric conditions. Unlike ozone or hydrogen-peroxide washes, cold plasma leaves nothing behind—just clean, safe cannabis.

What makes a decontamination method truly organic-compliant?

Because our process relies solely on oxygen from ambient air—no chemical additives, no ionizing radiation—it aligns with USDA Organic principles. Canadian regulators have likewise indicated that the technology fulfils their compliance criteria.

Can your method reach beyond the surface?

Cannabis buds are highly intricate; floral micro-structures can shelter contaminants deep within. By tuning gas composition, pressure and treatment cycles, our system delivers reactive species up to 10 cm into dense flower, ensuring deep-acting, adjustable decontamination far beyond surface level.

Rethinking Decontamination

Traditional cannabis decontamination methods may compromise quality or lack efficiency at scale. GOC’s cold plasma offers a non-thermal, chemical-free solution without ionizing irradiation, effectively eliminating bacteria and mold without residue, byproducts, or organoleptic damage. In an industry with high failure rates, this approach ensures compliance while preserving potency and the entourage effect.

Key Advantages

Efficient

Rapid treatment and scalable for high throughput.

Non-Destructive

No heat or irradiation means cannabinoids & terpenes remain unharmed (lab tests show potency retention).

Chemical-Free

Leaves no toxic residues, just clean, safe product.

Comprehensive

Effective against a broad spectrum of microbes (mold, bacteria, yeasts) meeting stringent pharmacological standards.

Deep Cleaning

Plasma generated in the exosphere and endosphere ensures thorough decontamination for comprehensive cleaning.

Targeted Treatment

Cold plasma preserves the intracellular integrity of the trichomes and safeguarding essential plant components.

Studies & Results

In recent trials, cold plasma treated cannabis showed an efficient log-4 reduction in total microbial count, with no loss in THC/CBD content. Terpene profiles remained unchanged, preserving the product’s therapeutic qualities. These results underscore the effectiveness of our approach.
