Air & Gas Specifications

Although we specialize in the analysis of thousands of compressed breathing air samples, we also provide services to customers with Non-Breathing Air and Pure Gas analysis. Whether you are establishing a management plan or testing to comply with a given specification, our knowledgeable staff can assist you by providing:

  • Analysis of pure gases such as Argon, Nitrogen, Nitrous Oxide, and Oxygen.
  • Air analysis for argon, carbon dioxide, carbon monoxide, condensed hydrocarbons, methane, nitrogen, nitrogen oxides, oil aerosol, oil vapor, organic compound identification and/or quantification, oxygen, particulates (particle size count and mass concentrations), sulfur dioxide, total halogenated hydrocarbons, total volatile hydrocarbons, and water vapor.
  • Design of Compressed Air & Gas Sampling Equipment specifically for your application if needed.
  • Research to determine if applicable standards are available.

Many of our customers have established their own criteria by monitoring the performance of the system over a given time period, reviewing literature/specifications, evaluating equipment parameters, and determining company objectives. After a thorough evaluation, specification limits are established and implemented into a management plan. The following are commonly used air & gas specifications. If the specification you need is not listed below, please Contact Us. We have many more air & gas specifications in our database. If you need a custom specification, Contact Us with your requirements, and we will provide a quote.

Carbon Dioxide TechNote

This TechNote from Trace Analytics, LLC discusses a high volume of samples that failed to meet a carbon dioxide level of 500 ppm. (CGA Grade E standard has been changed to allow 1,000 ppm.) The article contains valuable information on determining intake location and pipe size, molecular sieves & why they cannot consistently remove large amounts of CO2, pressure drops, and general guidelines for assuring a safe breathing air supply.
