Abstract
IN connexion with experimental work on the thermodynamic properties of binary mixtures of condensed gases, it was necessary to know accurately the triple point of argon on the absolute scale. Michels, Wassenaar, Sluyters and De Graaff1 have recently made a careful determination of this temperature using a platinum resistance thermometer. They suggested that it should be used as a fixed point for thermometer calibrations, and since this proposal has much to recommend it, it is desirable that there should be an independent estimate of the triple point.
