Product Name	Neon Gas (Ne) (5N Grade / Excimer Laser Grade)
CAS NO.	7440-01-9
Purity Specification (5N)	Assay: ≥ 99.999% • He (Helium): ≤ 6.0 ppm • H₂O (Moisture): ≤ 2.0 ppm • O₂ (Oxygen): ≤ 1.0 ppm • N₂ (Nitrogen): ≤ 2.0 ppm • CO + CO₂: ≤ 0.5 ppm • THC (Hydrocarbons): ≤ 0.5 ppm Strict control of Helium content for laser stability.
Key Applications	Critical noble gas for semiconductor and high-energy physics: Semiconductor Lithography (Top Use): Acts as the primary Buffer Gas (>95%) in ArF (193nm) and KrF (248nm) Excimer Lasers for DUV photolithography. Laser Technology: Active medium in Helium-Neon (He-Ne) lasers used for barcode scanning, alignment, and optical research. Cryogenics: Liquid Neon has 40x the refrigerating capacity of Liquid Helium per volume, ideal for specialized low-temperature cooling (25K to 40K range). Display & Lighting: Essential for high-voltage indicators, plasma displays (PDP), and iconic Neon signage (Red/Orange glow).
Cylinder Packaging	Standard Options: 10L Cylinder (~1.4m³ gas) 40L / 47L / 50L Cylinder (~6m³ - 7m³ gas) Valve Connection: CGA 580 / DIN 6 / JIS (Customizable) Material: Carbon Steel (Manganese Steel)
