The changing pace of environmental regulations worldwide, coupled with the dynamics of a highly competitive marketplace, produce an array of complex challenges for industries utilizing emissions-monitoring gases. Linde’s environmental monitoring products are designed to provide accurate, cost-effective, and safe solutions while meeting regulatory, service and delivery requirements. As a leading worldwide manufacturer of Specialty Mixtures, Linde can meet all your environmental monitoring needs, including:
Implicit in these solutions is Linde’s strength as the largest industrial gases company in North and South America and one of the largest worldwide.
Today, industry must carefully monitor its environmental emissions and use precise reference standards to obtain accurate measurements. Linde is a pioneer in producing highly accurate calibration gas standards and ultra pure zero gases for a wide variety of emissions applications.
Linde environmental solutions help ensure regulatory compliance, reduce emissions, increase capacity, improve economics and achieve a broad range of environmental benefits.
Stationary Source Emissions Monitoring

When NIST traceability is not required, Linde’s standard grades are available to meet your working gas requirements.
In addition to Primary, Certified and Non-Certified Standards, Linde’s unique Custom Standard allows you to specify the exact blend tolerance and analytical uncertainty for the mixture.
NIST Traceable Reference Materials (NTRM) – Certified by the National Institute of Standards and Technology (NIST) and accepted by the Environmental Protection Agency (EPA), as the highest accuracy standards commercially produced. These standards are the regulatory equivalent to NIST’s Standard Reference Materials (SRMs) and are made up of the same components and are within the same analytical range.
The NIST Traceable Reference Materials (NTRM) program was developed in a consortium with NIST, EPA, and industry participation. The program was intended to increase the availability of NIST traceable primary gas standards to industry. NTRMs supplement the supply of existing gaseous Standard Reference Materials (SRMs) and can be used wherever SRMs have been used in the past. These mixtures are similar in composition to NIST primary and SRM standards. However, because the concentration of the certified component can be bracketed by existing primary NIST standards, NTRM component concentrations can fall above, below or between existing SRM concentrations. This offers end users additional calibration reference points for greater accuracy and lower uncertainty measurements.
NTRMs are manufactured in a batch by Linde, with NIST assigning the component concentration. The NTRM program was designed to replace the EPA’s Certified Reference Material (CRM) program. EPA has stated that it accepts NTRMs in place of CRMs and allows their use as equivalent to SRMs for certification of emissions and production of mixture standards, such as EPA Protocols.
Available mixture components include:
EPA Protocol gas mixtures are required for the monitoring of emissions from stationary sources and are used for the calibration and Relative Accuracy Test Audit (RATA) of Continuous Emission Monitors (CEMs) as specified under EPA 600/R-12/531.
Linde EPA Protocols are NIST traceable with a ± 1% accuracy, produced in accordance with the latest EPA specifications. The benefits to you include:
The U.S. Environmental Protection Agency (EPA) regulations 40 CFR Parts 50, 58, 60, 75 and 266, state that the zero grade air or zero grade nitrogen used for Continuous Emission Monitoring (CEM) must contain no detectable concentration of the pollutant of interest. Furthermore, the zero gas should contain no contaminants that cause a detectable response to the analyzer or that suppress or enhance the analyzer’s response. If the zero gas is not certified to be free of critical contaminants, it could be out of compliance.
Linde’s CEM Zero Air and CEM Zero Nitrogen are developed to meet the stringent requirements of the U.S. EPA 40 CFR Parts 50, 58, 60, 75 and 266. Our manufacturing and certification specifications meet industry standards as well as federal, provincial, state and local regulations.
Linde’s CEM Zero Air and CEM Zero Nitrogen are packaged in aluminum cylinders. This standard size cylinder (AS) holds 145 square feet of air and 143 square feet of nitrogen. Larger and smaller containers are also available.
