Custom and Specialty Gas Blends

Concorde Specialty Gases on-site laboratory uses a high precision gravimetric scale and blending system to ensure the greatest quality stability of the gas mixture.

Specialty gas blends are used in a wide variety of process, manufacturing, and service applications that include industrial welding applications, food packaging, LASER installations, advanced medical procedures, environmental laboratories and more.

Concorde’s specialty gas blends undergo a series of rigorous purity tests and follows the exact mixture specifications to ensure their quality.

Primary Standard

• Primary Standard is the highest resolution blend made by weight.
• The primary mixture is certified to + 1% of each minor component when concentration is above 10 ppm.
• Mixture of concentrations between 1 ppm to 9.9 ppm it is certified to + 2% of each minor component.
• Mixtures of concentrations below 1 ppm it is certified to + 20% of each minor component
• Each cylinder has a certificate of analysis complete with certified concentrations.

Certified Standard

• Certified standard is certified to + 2% of each minor component for concentrations above 10 ppm and + 5% of each minor component for concentrations below 10 ppm.
• The blend tolerance for a minor component maybe doubled that of a primary standard.
• Each cylinder has a certificate of analysis complete with certified concentrations.

Custom Mixtures

• Custom mixtures are fall under gravimetric standard in which all minor components are certified by the weight values.
• Custom blends contain the same mixture preparation tolerance as the certified standard.
• Each cylinder has a certificate of analysis complete with certified concentrations.
