Abstract
In a process for producing a dye-containing polymer to be used for spectroscopic sample analysis, monomers are polymerized in the presence of a dye to form a block of bulk polymer. The bulk polymer or slices thereof can be easily measured in a spectrometer in order to determine the spectroscopic properties of the dye containing polymer. The bulk polymer is subsequently ground to particles which can be used to fill a fiber optical sensor. Since the particles have the same optical properties as the bulk polymer, the properties of the particles of dye-containing polymer of the sensor can be accurately determined from the bulk polymer.
