Abstract
A simple high pressure thermal conductivity gauge of good mechanical stability, freedom from poisoning effects and high accuracy has been described in detail. Its physical characteristics have been studied and optimum conditions for operation indicated. Its applicability to a wide variety of analyses is discussed and specific data quoted for those of the isotopic isomers of the lower aliphatic hydrocarbons and the hydrogens. Methods of direct calibration for the latter substances are indicated as well as a technique for their separation and purification. The theory of the gauge is developed and compared with experimental observations on the hydrogen isotopes.
