SENSING SYSTEM FOR DETECTING A SUBSTANCE IN A DIALYSATE

摘要

Embodiments of the present invention provide a sensing system for detecting a substance in a dialysate, the system inclucing: a hydrophobic barrier capable of allowing the substance in the dialysate to equilibrate to a gas; a detector capable of detecting the gas; an interface disposed between the hydrophobic barrier and the detector and configured to allow fluid communication of the gas; and one or more delivery mechanisms capable of transporting the gas from the hydrophobic barrier to the detector. A method of detecting ammonium gas in a dialysate is also provided.
