ABSTRACT A chemical method for the determination of testosterone in plasma is described. In this method testosterone is separated by paper chromatography. After further purification by chromatography on aluminum oxide a micro modification of the reaction of Koenig et al. (1941) is applied for quantitation. By the present procedure as little as 0.2 μg testosterone can be determined with adequate accuracy in appropriate plasma volumes.

AbstractWe propose a two-lattice method for direct determination of the recoilless fraction using a single room-temperature transmission Mössbauer measurement. The method is first demonstrated for the case of iron and metallic glass two-foil system and is next generalized for the case of physical mixtures of two powders. We further apply this method to determine the recoilless fraction of hematite and magnetite particles. Finally, we provide direct measurement of the recoilless fraction in nanohematite and nanomagnetite with an average particle size of 19 nm.
