Certified Standard Gas Mixtures

Certified standard gas mixtures are precise blends that offer traceability and certification by accredited calibration facilities and technicians. These gas mixtures are ideal for calibration equipment like monitoring sensors, analytical equipment and detectors across many industries. A highly precise mixture helps promote effective performance, compliance with regulations and equipment efficiency.

Specialty Gases for Custom Applications

In this section, you’ll find the common mixtures related to the basic segments of industries we routinely serve.

The EPA Protocol section lists common binary mixtures allowable under the most current Protocol document. We can also manufacture multi-component EPA Protocol mixtures commonly used in power plants. We offer the most extensive range of EPA Protocol gases in the industry and have adopted the extended shelf life for all Protocol mixes per the current document. If you don’t see it in the listing, simply contact us, and we will advise on the availability of any new Protocol request.

These mixtures are used as control atmospheres for the growth of aerobic and anaerobic biological cultures. Anerobic cultures thrive when deprived of oxygen. These gas mixtures contain less than 10 PPM of oxygen. Aerobic cultures require oxygen to survive. COA not included.

Global Calibration Gases provides a wide variety of multi-component hydrocarbon mixtures serving the natural gas, petrochemical and petroleum related products industries. We also manufacture multi-component mixtures containing a wide variety of volatile organic compounds (VOCs). The cylinder package selected is determined by evaluating the physical and chemical properties of the gas components in the mixture. Vapor restricted mixtures are evaluated using state of the art computer programs. We assess mixture stability to make sure the requested mixture does not contain components that may react with each other or the cylinder. We can safely manufacture mixtures containing combinations of fuels and oxidizers but these mixtures must be approved by our technical staff. We strictly limit fuel/oxidizer mixture concentrations to 50% of the lower explosive limit (LEL) of the fuel components in air. The following list is only a sampling of our capabilities. Please inquire if you do not see a component of interest on the list.
