- High-Purity CO₂ (≥99.99%)
Purified via cryogenic distillation and adsorption technologies, this ultra-refined grade ensures minimal impurities (<10 ppm moisture, <5 ppm hydrocarbons). Key applications include:
- Advanced Manufacturing: Critical for dry etching in semiconductor fabrication and cooling in laser systems.
- Scientific Research: Calibration gas for spectroscopy and supercritical fluid extraction (SFE) in pharmaceutical API synthesis.
- Healthcare: Controlled gas blends for respiratory diagnostics and cryopreservation of biologics.
- Food-Grade CO₂ (99.9% purity)
Certified to FDA 21 CFR and ISO 22000 standards, our food-grade CO₂ is ideal for:
- Beverage Carbonation: Precise fizziness control in soft drinks and craft beers.
- Food Processing: Modified atmosphere packaging (MAP) to extend shelf life, and dry ice for cold chain logistics.
- Decaffeination: Supercritical CO₂ extraction for caffeine-free coffee and tea production.
Both grades are available in cylinders, bulk liquid, or on-site generation systems. Supported by ISO 9001 certification and batch-specific GC-MS analysis reports, we guarantee traceability and compliance for your mission-critical operations.
