Abstract
A method includes flowing spent dialysate through a spent dialysate line of a dialysis system into a fluid receptacle fluidly coupled to the spent dialysate line, reacting the spent dialysate with a chemical reagent contained within the fluid receptacle to generate a reacted sample, emitting electromagnetic radiation through the reacted sample using an emitter; detecting a level of one or more waste products present in the spent dialysate using a spectroscopy sensor positioned proximate the fluid receptacle.
