Finnish Center for Alternative Methods (FICAM), since 2008 [111] FRANCOPA is the French platform dedicated to development, validation, and dissemination of alternative methods in animal testing. It was created on November 16, 2007. [112] The Italian Centro 3R was created in 2017. It is an interuniversity center dedicated to the promotion of the ...
The Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) coordinates U.S. federal government evaluation of new, revised, and alternative test methods. Alternative methods are methods for safety testing of chemicals and chemical products that use fewer or no animals or that minimize or prevent animal pain and ...
In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed. AAS can be used to determine over 70 different elements in solution, or directly in solid samples via electrothermal vaporization, [ 1 ] and is used in pharmacology , biophysics , archaeology and ...

For the analysis of volatile compounds, a purge and trap (P&T) concentrator system may be used to introduce samples. The target analytes are extracted by mixing the sample with water and purge with inert gas (e.g. Nitrogen gas) into an airtight chamber, this is known as purging or sparging.
The Carius halogen method measures halides quantitatively. [1] Chemical tests for cyanide test for the presence of cyanide, CN −; Copper sulfate tests for the presence of water; Flame tests test for metals; The Gilman test tests for the presence of a Grignard reagent; The Kjeldahl method quantitatively determines the presence of nitrogen
Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized ...
