METHOD AND APPARATUS FOR INDICATING QUENCH OF A LIQUID SCINTILLATION SOLUTION Abstract of the Disclosure A method and apparatus for indicating quench associa- ted with a liquid scintillation solution wherein the solu- tion includes a sample, a solvent and a solute. The method includes exposing the solution to flashes of light, detecting a pulse height spectrum for scintillations pro- duced in the solution in response to the light flashes, determining a unique point on such pulse height spectrum, and relating the unique point to a corresponding pulse height value, such pulse height value providing an indica- tion of quench associated with the solution. The wave- length of light preferably excites essentially only the solvent and the light flash intensity and duration is such that the pulse height spectrum produced in response to the light flashes does not overlap a pulse height spectrum for the sample in the solution. An attribute of the shape of the light pulse height spectrum may be examined to provide an indication of the homogeneous or non-homogeneous nature of the quench present in the solution.
