Quality Control

Our Acetylene (D1) is manufactured and handled under strict quality protocols to ensure consistency and safety for industrial use. Production adheres to relevant industrial gas standards, with purity and impurity levels controlled to meet specific application requirements. Certificates of Analysis (COA) detailing key parameters such as acetylene content, phosphine, and hydrogen sulfide levels are available upon request to support your quality assurance processes.

Storage

Acetylene is a highly volatile and flammable gas under pressure and must be stored and handled with extreme care. Preserve in approved, specially designed acetylene cylinders containing a porous mass and solvent (usually acetone) to ensure safe stabilization. Cylinders must be stored upright in a well-ventilated, cool, dry, and fire-resistant area, away from direct sunlight, heat sources, and oxidizing materials. Always use appropriate pressure-regulating equipment.
