Important Facts for Ordering Gas Mixtures

Our technical staff will be pleased to discuss your application, and the details involved in producing mixtures to your specific requirements. There are numerous restrictions in producing gas mixtures, a few of these are discussed in the following paragraphs.

• Reactive Gas Mixtures: Certain gases react with the internal walls of the cylinder, affecting the stability of the desired gas mixture. SpecAir uses treated aluminum cylinders for gas mixtures of this type. These specially prepared cylinders will maintain stability of reactive gas components such as SO2, H2S, NO, and NO2 in low concentrations.
  
  Some gases can react with others in the cylinder under high pressure conditions causing unstable mixtures or unwanted side products. If request a mixture of this nature, our Technical staff will advise you of possible side reactions and provide you with options.
  
• Mixtures of Oxidizers and Flammable Gases: Certain concentrations of flammable gases can be produced provided they meet certain safety criteria. A general rule is that the desired concentration does not exceed 50% of the lower flammability limit of the desired gas. Other mixtures are available provided the lie above or below the flammable range, or they are low in oxidizer content.
  
• Cylinder Pressure: Certain components with low vapor pressures can be mixed in the gas phase at reduced cylinder pressure. Mixtures of this type include many organic chemicals which are normally liquids at room temperature.
  
  Mixtures of this type will have a higher cylinder pressure as the desired concentration of the low vapor pressure components is reduced.
  
• Cylinder Outlet Connection: SpecAir chooses cylinder valve outlet connections in accordance with CGA guidelines. This system provides elements in safety and compatibility to protect both the user as well as the producer of the gas mixture. for all mixtures, the proper connections is determined after the composition and concentration has been specified.
