Static Magnetic Susceptibility Measurements on Small Solid Samples,ce Techniques series. The striking part of the setup is a vacuum microbalance with a sensitivity of about 10. dyne. The aim of this contribution is to emphasize the need for such a balance. This is achieved by discussing measurements. In particular an analysis of the apparent susceptibilities of an

Activation Energies of the Decomposition of Poly(methyl ,-phenylacrylate) from Static and Dynamic Tariant with extent of decomposition. In the case of poly(methyl .-phenylacrylate), which decomposes by random initiation and unzipping to monomer, this condition only applies with low-molecular-weight material. In polymers which contain long chains a termination step reduces E.. As the amount of ter

Apparatus for the Accurate Measurements of Magnetic Susceptibility with the Help of a Vacuum Electral Gouy method is the most favorable..A simple apparatus consisting essentially of a slightly modified Cahn RH Electrobalance, a permanent magnet, and thermostatic devices, is described. This apparatus can operate under high vacuum or in controlled gas atmosphere from −30 to 150 C with an accuracy a

Determination of the Diffusion Coefficient of Vapors by Means of a Microbalance,ed by using a recording microbalance. The determination is performed by recording the loss of weight of a small bucket containing a liquid evaporating through a narrow vertical tube. The suspension wire is placed in the axis of the tube. In the case of very narrow tubes (Ø < 10. m), tube and contain

Microweighing in Vacuo with the Aid of Vibrations of a Thin Band,ation depends on both tension and mass distribution. Let us assume that the band is loaded by a thin layer of dust, formed by spraying or electrostatic precipitation. In this case, the natural frequency will be diminished. This is shown in Fig. 1, where the natural frequency of a plastic band with a

Some Uses of Wire-Suspended Microbalances, change in pressure or volume of the gas (volumetric method). The former method offers a number of advantages, particularly the directness of the measurement, over the latter. These are illustrated in the course of the present paper, which is concerned with the application of a microbalance of the G
