Abstract
One or more properties of a refrigerant are analyzed by evacuating a refrigerant sample vessel, drawing a refrigerant vapor sample into the vessel, and condensing the refrigerant sample within the vessel for measurement and indication of one or more desired properties of the liquid refrigerant sample. By drawing the sample refrigerant in vapor phase rather than liquid phase, the sample will be relatively free of lubricant, particulate or water contamination. The sample vessel can be readily cleaned by simple evacuation in preparation for the next measurement cycle.
