Book Description
Excerpt from Application of the Interferometer to Gas Analysis The principle of the gas interferometer and its method of us in gas analysis is discussed in connection With the calibration of the instrument. The effect produced upon the observations by variations 111 gas composition and experimental conditions is analyzed and equations developed by. Which the magnitude of such changes can be estimated. T ypical cases in Which the inter ferometer may be employed, such as for the analysis of mixtures containing helium, analysis of flue gas, etc., are given together With points on sources of error, details of opera tion, and the relative sensitivity of the interferometer for different gases.

Book Description
Excerpt from Experiments With the Displacement Interferometer Among the subjects selected for treatment was the horizontal pendulum. In the first part of Chapter I certain available forms of the pendulum, with and without a float, are considered and tested as to their discrepancies, through long lapses of time, by a reflection method. Among the interesting results obtained is the suggestion of an apparatus capable of measuring changes of elongation to the amount of even less than 4xi0'1 of the total length per vanishing interference ring. In the second part of the chapter the interferometer itself is used, a service able method of application worked out, and the range of application studied through many months. With a relatively very Wide scope (several seconds of arc) there should be no difficulty, under proper surroundings, of measuring changes of inclination as small as 3 X 10 - 4 seconds of arc per interference ring, and it is probable that one could reach smaller angles by modifying parts of the pendulum. In Chapter II an attempt is made to use this interferential horizontal pen dulum for the measurement of the gravitational attraction of two parallel disks. What was obtained, however, was a definite repulsion of the disks, decreasing with their distance apart and appreciable even within mm. Of this distance. As the method of measurement contemplates the viscosity of the film of air between the disks, and as the efiect of any natural charge or potential would be insignificant in comparison with the forces observed, it is probable that the repulsion in question is attributable to the molecular atmospheres by which the disks are surrounded in air, supposing that such atmospheres of gas increase in density as the surface of the disk is approached. Chapter III is introduced as a severe test on the interference equation employed for the case of path differences resulting when glass columns as much as 10 inches long are inserted in one of the component beams of the displacement interferometer. It appears that the constants of any dispersion formula may be obtained directly from these observations. The equations for the relations of displacement and wave-length increments show, however.

Book Description
Excerpt from Methods of Gas Analysis In publishing my "New Methods for the Analysis of Gases," it was not my intention to write a manual of gas analysis, but merely to describe my own researches and the construction of apparatus. My present plan, however, after ten years' experience and the most varied work with gases and their analysis, is to describe all of the operations which are involved in the analysis of gases with my apparatus. I have thought to give the book especial value by limiting myself to the description of those methods which, in my opinion, are at the present time the most practical. I have not endeavoured to give a complete description of all known methods, because the book would then become too bulky to be used as the laboratory guide which it is intended to be. The apparatus devised by Pettersson has been described, because a wholly new principle in the measurement of gases is there brought into use. In the following pages I hope to give a guide to gas analysis by the help of which the various examinations, even the most difficult, can be carried out.
