[3] [4] [5] His work at OCME with Charles Norris, the chief medical examiner, created the foundation for modern medicolegal ...
Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting.

He had received a Ph.D. in chemistry at the age of 22 and was an expert in photography and forensic science. In 1906 he was appointed a professor of forensic science at the University of Lausanne . In 1909, he was the founder of the first academic forensic science programme and of the "Institut de police scientifique" (Institute of forensic ...
Orfila created new techniques, refined existing techniques and described them in his first treatise, Traité des poisons (1813), greatly enhancing their accuracy. In 1840, Marie Lafarge was tried for the murder of her husband. Although she had had access to arsenic, and arsenic had been found in the victim's food, none could be found in the corpse.
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

The Marsh test is a highly sensitive method in the detection of arsenic, especially useful in the field of forensic toxicology when arsenic was used as a poison. It was developed by the chemist James Marsh and first published in 1836. [1] The method continued to be used, with improvements, in forensic toxicology until the 1970s. [2]
