What Are Specialty Gases?

Specialty gases are gases that are specifically engineered to meet high-purity standards and tailored for particular applications. They are typically used in industries where precision and reliability are critical, such as electronics, healthcare, and manufacturing. These gases are characterized by their high purity, often with impurity levels below 0.0001%.

How Are Specialty Gases Classified?

Specialty gases can be categorized into several types based on their properties and uses:
High-Purity Gases: Such as high-purity nitrogen and oxygen, used in semiconductor manufacturing and electronics.
Standard Gases: These are gas mixtures used for calibrating analytical instruments.
Rare Gases: Including helium and argon, used in lighting and cryogenic applications.
Medical Gases: Such as medical oxygen and carbon dioxide, used for therapeutic and diagnostic purposes.
Industrial Gases: Like acetylene and propane, used for welding and cutting.

What Distinguishes Specialty Gases from Commodity Gases?

The primary difference between specialty gases and commodity gases lies in their purity and quality control. Specialty gases are produced to meet stringent purity standards, ensuring they are free from contaminants that could affect their performance. In contrast, commodity gases are used for general industrial purposes and have lower purity requirements.
