Landfill Gas Testing


As one of a few laboratories suited with the necessary capabilities, we take on every landfill gas challenge with a mission of coordinating and executing the most successful engagement for our clients.

Landfill gas testing is incredibly difficult, as it can be highly corrosive, presenting various interferences during analysis. The Enthalpy Analytical team is one of a few laboratories with the capabilities to tackle this matrix.

We understand the importance of reproducible and defensible data, and we care tremendously about our service. Our talented project management team and skilled technical experts coordinate closely with each other and the client to create a highly-specific analytical approach for any project.

As technology, methodologies, and regulations continue to evolve, our dedicated technical and quality control teams work diligently to ensure that the laboratory is on the cutting edge of analytical capabilities. This, combined with our dedication to tackle even the toughest challenges, makes the Enthalpy Analytical team one of the most trusted, reliable, and responsible laboratories available. What truly sets us apart, however, is our commitment to each client and the value we place on these relationships.

Our laboratories offer comprehensive landfill gas services with options to meet any need you have.

NCASI Test Methods

  • The National Council of Air and Stream Improvement (NCASI) has maintained itself as an independent non-profit research organization founded by the wood products industry in 1943. In the absence of adequate air and water test methods relevant to the analytes and source types found at wood products facilities, NCASI began developing and publishing air and water test methods in the 1990s.Our people have been proactive in understanding, executing, and adding these methods to our NELAP scope of accreditations as they become available. We have developed a thorough understanding of the in-lab and in-field performance measures for each method in order to help validate a test program.NCASI Methods primarily focus on the sampling and analysis of alcohols (methanol, phenol) and aldehydes (formaldehyde, acetaldehyde, acrolein, propionaldehyde). The suitability of NCASI test methods goes beyond wood products facilities, and they are often used for engineering as well as compliance testing.
