Lattimer and Harris. have reviewed a number of mass spectral techniques that have been successfully applied to the analysis of rubber additives, either by direct analysis of the polymer surface or indirectly after extraction of the rubber ingredients by using a solvent, for example.

The vertical scale of a Mössbauer spectrum is given in percent transmission or percent absorption and the spectral absorption area is an important quantity for the Mössbauer spectroscopist. This area is a measure of the recoil-free fraction of the absorber, which is the fr

Also, a good fundamental experimental knowledge of impuri ties present in the final material helps the investigator get more
