Application Note: Liquid Scintillation

From Hamilton Co.
 

 

Liquid scintillation provides a method for analyzing the concentration of radioactivity in an unknown sample. Detection is achieved by converting the kinetic energy of a nuclear emission into light energy. This conversion is accomplished by adding a scintillation cocktail to an unknown sample. Solvent molecules in the scintillation cocktail become excited by the radiation which results in the excitation of a fluorescent molecule. When the fluor molecule returns to its ground state a blue flash of light is emitted. The light is captured by a detector and recorded as a radioactive emission called a count.

Liquid Scintillation Sample Preparation with the ML500 diluter:
The ML500 is used to create standards and prepare sample dilutions for Liquid Scintillation.
The following key features make the ML500 ideal for this application:
* A borosilicate glass and PTFE fluid path to minimize sample carryover
* Stored methods to eliminate the chance for operator error
* A logging feature in the software to record all pump operations
* Small volume accuracy to increase reproducibility
