For 10 points, name this class of methods which attempt to determine the composition and percent masses in a molecule.
Wolfgang SchÃ¶niger's oxygen flask method and Lassaigne's sodium fusion test are older forms of methods with this goal. The Pregl-Dumas method is typically used in automated systems for performing this task. Graphite furnaces are used to atomize samples for methods of performing this task. EDX and PIXE are techniques that achieve this goal, while owners of high flux neutron sources can perform a nondestructive method of this sort through neutron activation analysis. Inductively coupled plasma produces superior (*) emission spectra than flames for the purpose of this task. The most common method of this task involves burning a sample in an excess of oxygen and measuring how much carbon dioxide, water, and nitric oxide is produced and is known as CHN analysis.
