The experiment tests a simple instrument (DTM DIAPASON) for the study of nano-particles migration and capture, achieved by very small thermal gradients. The particles range from 2 nm to 1 micron. This range allows the monitoring of combustion-generated pollution, the analysis of hostile environments, and the identification of atmospheric contaminants.Principal Investigator(s)

The scientific instrument DIAPASON has been extensively and successfully tested on ground (several different ambient situations), but not in microgravity.
DTM is studying a scientific phenomena based on nano-particle migration and capture achieved by very small thermal gradients. The particle dimensions that can be ?trapped? thanks to recently designed hardware range from one micron to one thousandth of a micron. This range is very meaningful in many fields. Some examples are:
The information achieved by testing DIAPASON aboard the ISS are very helpful to investigate possible pollution of the ISS environment (several checks can be performed in different ISS modules). From the results analysis, on ground, suggestions can also be given on how to improve the atmosphere were the astronauts leave during their Space mission.Earth Applications
DTM DIAPASON is mainly focused on Earth needs (monitoring of pollution in large crowded cities, industrial environment, hostile environment like chemical plants, pipelines boosting stations, combustion facilities, nuclear plants, offshore installations..). Anyhow, microgravity experimentation shall provide to DTM technicians new data allowing them to further improve the functionality of this light and very accurate science instrument.
