Color plate 1 9 Weighing by difference the old-fashioned way. (a) Zero the balance, (b) Place a weighing bottle containing the solute on the balance pan. (c) Read the mass (33.2015 g). (d) Transfer the desired amount of solute to a flask, (e) Replace the weighing bottle on the pan, and read the mass (33.0832 g). Finally, calculate the mass of the solute transferred to the flask 33.2015 g — 33.0832 g = 0.1131 g. (Electronic balance provided by Mettler-Toledo, Inc.)...

The Mettler-Toledo Inc., SDTA 861 DMA analyser [6] is capable of providing DMA measurements over wide frequency ranges (from 1 mHz to 1 kHz) and large dynamic stiffness ranges. A schematic of the instrument is illustrated and examples are presented of test data for various rubbers obtained using this equipment.

One group of TGA instruments with direct contact thomal sensors is the Mettler-Toledo, Inc. TGA851 series of thermograwmetric analyzers (Figure 2). These instruments incorporate two temperature sensors, one for temperature control and the other in direct contact with the bottom of the crucible. Direct contact with the crucible provides direct sample temperature measurement and allows the investigation of the sample temperature as functions of furnace response, specimen mass, crucible material, heating rate and transitions. 

All experiments are performed on a Mettler-Toledo, Inc. TGA85I. The SDTA routine of the TGA85T measures the temperature difference as described in Equation 9. By virtue of the direct contact thermal sensor, a reference temperature is calculated from a complete set of calibrations. Alternatively, the results of an experimental reference (normally an empty crucible on the support) can be used. In this study the latter method is...

Experiments were performed to characterize the temperature responses of TMA furnaces as fimctions of position within the furnace, specimen length, specimen heat capacity and heating rate. Two instruments were used in this study, the TMA840 from Mettler-Toledo, Inc., (heretofore referred to as TMAl) and another commercially-available TMA (heretofore referred to as TMA2). The latter instrument is representative... 

Two substances were used as temperature indicators, indium metal (>99.99% pure from Mettler-Toledo, Inc.) and 0.05 mm thick polycarbonate film. Indium specimens were cut from indium pills which had been pressed to 20-250 pm thick. The indium specimens were sandwiched between two pieces of aluminum foil to protect the fixtures.
