A pair of calibrated cylinders are connected by means of an interconnecting valve with an inlet valve at one end of one cylinder and a pressure gauge connected to one end of the other cylinder. The first cylinder is filled with condensable coolant containing a noncondensable gas contaminant and is valved off to the atmosphere. When the interconnecting valve between the cylinders is opened the condensable coolant and noncondensable gas are allowed to volatilize into the other cylinder until thermal equilibrium is established between both cylinders. The absolute pressure, which is equal to the sum of the partial pressure of the noncondensable gas and the known vapor pressure of the coolant at the equilibrium temperature, allows the quantity of noncondensable gas to be determined using Henry's Law.
