THE DIFFUSION-BONDED SENSOR; THE FUTURE OF TEMPERATURE AND HEAT FLOW MEASUREMENTS TECHNOLOGY Diffusion bonding of metals is accomplished by placing two metal surfaces in contact at an elevated temperature and pressure. Over time, diffusion of the metals occurs at the atomic level, producing an intimate, continuous, high-quality bond. In the Discovery DSC, chromel and constantan are diffusion-bonded to produce the perfect thermocouple. In the resultant transducer structure, the diffusion bond is positioned just below the sample surface, in the perfect position. The measurement is less...

APPLICATIONS Sensitivity & Resolution There are countless ways to measure the sensitivity of a DSC, and test methods are often exploited to promote performance under a specific set of conditions. However, experienced thermal analysts know that the best DSC provides sensitivity under all experimental conditions. The Discovery DSC delivers the highest sensitivity for a diverse range of heat flow transitions, across a wide range of experimental scanning rates. This is accomplished through the combination of transducer innovations and our patented Tzero® technology which flattens the baseline,...

DISCOVER EFFORTLESS REPEATABILITY IN HEAT FLOW MEASUREMENTS Figure A 22 mg Sapphire Disc, 20 ˚C/min. Many applications require not only the measurement of accurate heat flow, but also quantitative heat capacity. Heat capacity is the fundamental intrinsic property of a material which gives rise to heat exchange, and is an incredibly sensitive indicator of structural morphology in a sample. Historically, heat capacity measurements were performed using a three-run or step-iso method. In addition to the sample measurement, additional runs were necessary to account for baseline artifacts and...
