  3. Atomic absorption spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_absorption_spectroscopy

    AAS is based on the absorption of light by free metallic ions that have been atomized from a sample. An alternative technique is atomic emission spectroscopy (AES). In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed.

    en.wikipedia.org/wiki/Test_method

    A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. [ 1 ] In order to ensure accurate and relevant test results, a test method should be "explicit, unambiguous, and experimentally feasible.", [ 2 ] as well as ...
