Title: Junichi Iwamura: Innovator in Organic Compound Isolation
Introduction
Junichi Iwamura is a notable inventor based in Kashiwara, Japan. He has made significant contributions to the field of organic chemistry, particularly in the isolation of barely volatile organic compounds. With a total of 6 patents to his name, Iwamura's work has implications for environmental analysis and chemical measurement.
Latest Patents
Iwamura's latest patents include a method for the isolation of barely volatile organic compounds. This innovative method involves continuously adding superheated steam and a volatile, hardly water-soluble solvent to a sample suspected of containing organic compounds, such as dioxins. The process includes distilling off an azeotropic mixture of the organic compound and the solvent through steam distillation, followed by the separation of the solvent and water phases. This method allows for the quantitative recovery of the organic compound for further analysis, such as gas chromatography and high-resolution gas chromatography-mass spectrometry.
Another significant patent by Iwamura is a method for measuring catalase activity in samples. This method involves treating the sample with peroxide, alcohol, nicotinamide adenine dinucleotide (NAD), and aldehyde dehydrogenase. The process produces an aldehyde corresponding to the alcohol and converts NAD to its reduced form (NADH). The absorption of radiation at the characteristic absorption band of NADH is then measured to determine catalase activity.
