Description
Summary:Advanced approaches to the development of analytical modules for water quality on-line monitoring during long-time orbital piloted missions are discussed. The first module is intended for an analysis of water ionic composition and its microbiological toxicity with individual selective sensors. The second module operating with the use of an oxythermographic method ensures recirculating water monitoring for the content of total carbon and specific hydrocarbons, e.g., ethanol. Both modules represent subsystems of an integrated analytical complex for an on-line control of air and water quality onboard spacecrafts. •Oxythermography and electronic tongue – new instruments of water quality control in space ships.•Multivariable data are processed with the use of chemometrical methods.•Possibility to measure of total carbon in water using oxythermography.
