摘要：
Disclosed is a sensing system for detecting a substance in a dialysate. The sensing system comprises a hydrophobic barrier, a detector (141), an interface (40a, 40b) and one or more delivery mechanisms (151). The hydrophobic barrier is capable of allowing the substance in the dialysate to equilibrate to a gas. The detector (141) is capable of detecting the gas. The interface (40a, 40b) disposed between the hydrophobic barrier and the detector (141) and configured to allow fluid communication of the gas between the hydrophobic barrier and the detector (141). The one or more delivery mechanisms (151) are capable of transporting the gas from the hydrophobic barrier through the interface (40a, 40b) to the detector (141). The one or more delivery mechanisms (151) allow the gas to move either back and forth within the interface (40a, 40b). The substance is ammonium and the gas is ammonia gas, and the gas is in a pH dependent equilibrium with the substance in the dialysate.
