Other Methods Available:
ASTM D1945 Determination of BTU content
The determination of Net and Gross Heating Value, generally for Landfill Gas based on the Method 3-C analysis per U.S. EPA guidance documents. Analyzed from a canister.
Nitrous Oxide (Modified Method 3C)
Includes nitrous oxide in addition to the carbon dioxide and methane normally associated with the Method 3-C target compound list analyzed from a canister.
Methane/Ethane (Modified Method 25/25-C)
The analysis of a canister for methane and ethane. Due to the modifications to the analytical program, ethane cannot be included in either the Method 25 or Method 25-C target compound list because it can have unknown impacts on the reported NMOC concentrations.
Methane only (Modified Method 25/25-C)
The analysis of a canister for methane and no other compounds. This is also normally included in the Method 25 and Method 25-C target compound list.
EPA Method 10B - Determination of Carbon Monoxide Emissions from Stationary Sources
The analysis of a canister for only carbon monoxide and no other compounds. This is also normally included in the Method 25 target compound list and can be added to the Method 25-C target compound list upon request.
EPA Method 204 Distillations
Rotovap distillation of coating/paint for determination of response factor. Guidance calls for the use of the same analyzer for RF determination as was used for the field analysis. Generally 2 ml of distillate returned per sample.
