title: Liquid oxygen contaminants--increase in concentration during use of domiciliary liquid oxygen medical systems.
abstract: The quality of liquid oxygen in domiciliary medical systems used for oxygen therapy was investigated during the emptying cycle under simulated breathing conditions. The increase in the levels of contaminants during the use of these systems was evaluated by gas chromatography and two sampling methods. The quality of liquid oxygen from storage tanks located in hospitals and in the production or in distribution plants was also investigated.
