Outgas Analysis System
QTGA, an evaluation method assuming space environments Outgas analysis system

Joint research

NIHON DEMPA KOGYO CO., LTD. has developed a new outgas analysis system to quantitatively and qualitatively analyze the outgas emitted from organic materials in vacuum environments, such as adhesives glues, heat dissipation materials, and resins, as a result of joint research and development with Japan Aerospace Exploration Agency (JAXA).
