Abstract:
1. A system for preparing a refrigerant sample for analysis comprising: (i) a pressure regulator assembly including a pressure regulator and a means for heating a refrigerant sample contained within an interior region of the pressure regulator, said pressure regulator defining an inlet through which the refrigerant sample is delivered from a refrigerant sample container and an outlet through which the refrigerant sample is expelled; (ii) a filter assembly having: (iii) a refrigerant analysis system that is fluidly coupled to the analyzer outlet of the filter assembly for analyzing the composition of the refrigerant sample; (iv) a vacuum source that is coupled to each of the filter outlets of the filter assembly for drawing the refrigerant sample out of the filter assembly; and (v) a venting container that is fluidly coupled to each of the filter outlets of the filter assembly for receiving and storing the refrigerant sample from the filter assembly wherein the venting container is separate from the refrigerant sample container and the vacuum source.
