Pure Ge-132 Germanium is a unique organogermanium compound, bis-carboxyethyl germanium sesquioxide, sometimes called just germanium sesquioxide. It has unique molecular characteristics which make it virtually unreactive in the body, and its small particle size and unique structure permit it to be readily cleared in the urine as the intact molecule. Allergy Research Group® introduced pure germanium into the United States in 1986. They recognize the importance of providing pure and tested Ge-132. To assure the quality and purity of our germanium products, they carefully analyze every lot. Testing procedures include identification by infrared spectroscopy, purity by acid group titration, and absence of inorganic germanium impurities by color limit test.*
