Major industrial gas player Taiyo Nippon Sanso Corporation (TNSC) has continued to progress with its oxygen-18 enrichment method using oxygen (O2) cryogenic separation technology.
Further progress was made with the method during a project undertaken by the company to study the changes in daily energy expenditure with ageing in humans, the results of which were published in the Science journal of the American Association for the Advancement of Science in August.
The study involved the provision of the stable isotope of oxygen-18 to selected participants, as required by the “doubly labelled water method” used during the research. The isotope is also needed for stable isotope analysis in biological samples such as blood, urine and saliva, part of the company’s development of a “gold standard” for measuring total energy expenditure.
