Over 3,000 units deployed with OES and ICP spectrometers, significantly reducing high-purity argon costs.
Dual-tower multi-port valve design requiring no hydrogen or vacuum for regeneration, ideal for metallurgical shielding gas.
Accepts feed H₂ with up to 1,000 ppm O₂—using low-cost industrial hydrogen for electronics, semiconductors, and optical fiber.
Purifies cylinder industrial O₂ into high-purity oxygen for IR carbon-sulfur analyzers, electronics, optical fiber, and lab instruments.
Dual pre-adsorption towers cascaded with a high-temperature alloy N₂-removal tower, achieving ≤ 0.2 ppm residual N₂ for semiconductor use.
Five-zone precision temperature control covering Ar, He, Ne, Kr, and Xe with up to 6N ultra-high purity output.
LLM natural-language direct reactor control with Bayesian optimization linked to online GC characterization.
Refurbish rather than scrap aging units—piping renewal, precision calibration, full commissioning, and performance upgrades.
Multi-stage catalytic oxidation and deep molecular-sieve capture for tritium removal from exhaust streams.
Five-channel gas mixing, 900 °C fluidization, and five-layer filter gas-solid separation with fully sealed collection.
Program-controlled valve internal-leak remediation, dense molecular-sieve packing, and step optimization to restore purity and yield.
Pre-emulsification with semi-continuous gravimetric dosing, ±0.3 °C anti-runaway thermal control, and dual-reactor skid delivery.
Three adiabatic beds in series with interstage quench, gas-liquid dual-phase feed, and Ex d IIB T4 explosion-proof skid.
LLM voice control of valves, MFCs, and multi-zone furnaces, coupled with online GC for real-time conversion/selectivity and 24/7 closed-loop Bayesian optimization.
Multi-stage catalytic oxidation and molecular-sieve capture, 3-channel ionization chamber tritium monitoring with H₂/CO interlocks, 316L EP orbital-welded VCR piping, leak rate ≤ 1×10⁻⁹ Pa·m³/s.
