Das β-γ-Photometer als einfaches Hilfsmittel zur Elementaranalyse von Lösungen und organischen Substanzen

Abstract

The “β-γ-Photometer” was designed to effect the determination of the carbon/hydrogen relation of organic substances as well as analyses of elements with higher atomic numbers, like sulfur, chlorine, phosphorus, but also lead for instance, in organic compounds and aqueous solutions. The described method does not require any chemical preparation. The limits of determination depend on the element which has to be determined and on the radiation source which has been used. The following values may be indicated for example: When determining the carbon/hydrogen relation, a difference in the hydrogen portion up to 2‰ is still detectable. A difference in the weight portion of sulfur and chlorine can be detected up to 0,1‰, and 0,05‰ of iodine. The method is mainly suitable to control chemical processes where series of samples of similar composition are to be tested.
