Quality Control

Our Neon is produced and handled under stringent quality management protocols to ensure consistent purity and performance. We offer various grades, including high-purity and research grades, with specifications tailored to meet the demands of lighting, electronics, and cryogenic applications. A Certificate of Analysis (COA) detailing purity, impurity levels, and other critical parameters is provided with every shipment to guarantee supply reliability and technical compliance.

Storage

Preserve in a tightly closed container, protected from light. Compressed gas cylinders must be stored upright in a well-ventilated, secure area away from heat sources and flammable materials. Store at ambient temperatures, avoiding extremes. For refrigerated liquid neon, specialized cryogenic containers are required. Keep container valves closed when not in use and ensure proper labeling and handling procedures are followed according to local and international regulations for pressurized gases.
