Ernest rutherford and Gas Chromatography

Rutherford, Ernest, 1st Baron Rutherford of Nelson and Cambridge (1871-1937), British physicist, who became a Nobel laureate for his pioneering work in nuclear physics and for his theory of the structure of the atom. Rutherford was one of the first and most important researchers in nuclear physics. Soon after the discovery of radioactivity in 1896 by the French physicist Antoine Henri Becquerel, Rutherford identified the three main components of radiation and named them alpha, beta, and …

…their results are evidential (capable of providing evidence in court). Blood-alcohol level can also be determined by actual blood tests, usually through gas chromatography. In this method, the blood sample is vaporized by high temperature, and the gas is then sent through a column that separates the various chemical compounds present in the blood. Gas chromatography permits the detection not only of alcohol but also of other drugs, such as barbiturates, cocaine, amphetamines, and heroin.
