FAQs

What is the shelf life of your standard gases

Most mixtures have a shelf life of 1-2 years. This is the period during which the concentration remains within the certified tolerance

Why do Excimer Laser gases (ArF, KrF) need special cylinders

These contain highly active $F_2$ or $HCl$. We use Advanced Passivation Technology to create an inert film on the cylinder wall, preventing gas-metal reactions and ensuring stability

What information is included in the COA

The Certificate of Analysis includes actual concentration, preparation tolerance, analytical uncertainty, filling pressure, valve type (eg., CGA 679), and expiration date

What is the difference between Preparation Tolerance and Uncertainty

Preparation Tolerance is the allowable deviation from your target concentration, while Uncertainty represents the precision of our laboratory's measurement of the final product

Can I use the gas until the cylinder is completely empty

No. Always leave a residual pressure of 0.5 - 1.0 MPa. This prevents ambient air and moisture from entering and contaminating the cylinder for future use

What are the storage requirements for high-pressure cylinders

Store in a cool, ventilated, and dry area below 45°C. Keep cylinders upright, secured, and away from direct sunlight or heat sources

Are your standard gases traceable

Our standard gases are strictly traceable to the National Institute of Metrology (NIM), ensuring global consistency and compliance with ISO 6142 standards
