Utilization of Monolithich Solid phases for sample preparation and processing

This proposal addresses the issue of sample preparation technologies which can be utilized in ocean world missions to enhance the sensitivity and selectivity in the analyses of collected samples. On Earth, solid phase matrices are utilized extensively for capture, separation, and selective retention of components in the sample analysis process. Utilization of solid phases for similar processes is not yet possible on other world based missions due to a lack of investigations into the compatibility of these materials with space flight and deployment under other world conditions. This Phase I effort seeks to investigate commercially available solid phase substrates for three sample processing methods that would be directly integrated into existing NASA programs; these methods are solid phase extraction (SPE), desalting, and ion exchange. This effort will evaluate the performance of different substrates and surface coatings through stresses expected to be experienced on space deployment. The goal is to determine which substrates/surfaces might be able to play a role in future sample analysis missions that are planned for exploration of ocean worlds. More »
