The book also provided methods and logic to estimate if a death resulted from suicide, accident or murder. Inorganic analysis, which is performed on all substances that do not contain carbon, employs spectrophotometry, neutron-activation analysis (a technique involving chemical analysis by radioactivity), and X-ray diffraction, among other techniques.
