- Design concepts for the International Space Station Water Processor (WP) will be validated as discrete flight experiments on-board the Space Shuttle Spacehab. This paper summarizes the results of a study into sample stability within a modified Teflon cell culture bag assembly to support an upcoming Spacehab evaluation of the WP Volatile Removal Assembly (VRA). Results indicate that a lack of adequate preservation results in significant sample analyte degradation over the course of 2-3 week due to increased microbial activity. Results were utilized for the definition of an optimal preservation approach based on the anticipated VRA Flight Experiment samples.
