Graphite Furnace Atomic GFAA Spectroscopy Waste and Cleanup Risk Glossary and Key Word Absorption Spectroscopy Assessment Glossary List Definition: Graphite furnace atomic absorption (GFAA) spectroscopy is a highly sensitive spectroscopic technique that provides excellent detection limits for measuring concentrations of metals in liquid sample media. Water samples may be analyzed directly, while soil samples first must undergo an extraction process to draw the contaminants into solution for analysis. The sample is vaporized in the graphite furnace, and light of a specific wavelength then is passed through the atomic vapor of an element of interest. The attenuation of the intensity of the light as a result of absorption is measured, and the amount of attenuation is converted into an estimate of the contaminant metal's concentration.

Term Acronym Vocabulary Vocabulary Type Preferred Term Definition: A greenhouse gas auto standard establishes fleet average GHG emission requirements for vehicles, such as passenger cars and light trucks. Expressed in carbon dioxide (CO2) equivalents, the standard can take into account GHG emissions directly emitted (e.g., operation of vehicle, leakage of refrigerants from AC unit) and upstream emissions associated with the production of the fuel used by the vehicle. Greenhouse Gas GHG Inventory State and Regional Policy Glossary and Key Word Inventory Tracking Definitions List Definition: A greenhouse gas (GHG) inventory is an accounting of the amount of GHGs emitted to and removed from the atmosphere over a specific period of time (e.g., one year). A GHG inventory provides information on the activities that cause emissions and removals, as well as background on the methods used to make the calculations. Greenhouse Gas GHG Performance State and Regional Policy Glossary and Key Word Performance Standard Standard Tracking Definitions List Definition: A power sector greenhouse gas (GHG) performance standard is a requirement that all new power plants have emission characteristics equivalent to or better than the established standard (e.g., the most efficient combined cycle plant). Greenhouse Gas GHG Registry State and Regional Policy Glossary and Key Word Registry Tracking Definitions List Definition: A greenhouse gas (GHG) registry is an official repository to which an entity reports emissions of one or more GHGs or changes in emission levels, typically annually. Participants can include companies reporting entity-wide or on a project-by-project basis; all or parts of state government operations; individuals; or other parties responsible for emissions or emission reductions. A GHG registry is subject to reporting and verification requirements to ensure data consistency and quality, and registries can support voluntary or mandatory reporting requirements.

Graphite Furnace Atomic GFAA Spectroscopy EPA EV-Research- Taxonomy Absorption Spectroscopy Research Resources- Dedicated Science Technologies &Equipment Definition: Graphite furnace atomic absorption (GFAA) spectroscopy is a highly sensitive spectroscopic technique that provides excellent detection limits for measuring concentrations of metals in liquid sample media. Water samples may be analyzed directly, while soil samples first must undergo an extraction process... to draw the contaminants into solution for analysis. The sample is vaporized in the graphite furnace, and light of a specific wavelength then is passed through the atomic vapor of an element of interest. The attenuation of the intensity of the light as a result of absorption is measured, and the amount of attenuation is converted into an estimate of the contaminant metal's concentration.
