Differential Scanning Calorimeter (DSC)
The Discovery DSC represents the latest innovation from TA Instruments. Building on the Tzero® technology first pioneered in its Q Series™ instruments, the Discovery DSC introduces its innovative Diffusion-Bonded Sensor technology. This technology represents the future of temperature and heat flow measurements. The Discovery DSC provides unmatched precision, accuracy, industry-leading sensitivity and resolution. The result is a Differential Scanning Calorimeter which improves every aspect of DSC performance…
DISCOVER THE DIFFUSION-BONDED SENSOR; THE FUTURE OF TEMPERATURE AND HEAT FLOW MEASUREMENTS
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, and 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 sensitive to pan placement effects thereby maximizing repeatability. Unlike alternative designs which employ discreet sensor points, the Diffusion-Bonded Sensor represents a continuous thermo sensitive surface, dramatically improving sensitivity of the temperature measurement while maintaining a very short time constant for excellent signal resolution.
THE DISCOVERY DSC INCLUDES MULTIPLE INNOVATIONS DESIGNED TO INCREASE PERFORMANCE AND STABILITY
Uniblock Silver Furnace
The Uniblock furnace is precisely machined from a single block of silver, providing temperature uniformity and ensuring thermal homogeneity. The result is reduced thermal gradients, increased ruggedness and improved measurement precision.
Temperature Controlled Electronics
The Discovery DSC cell processes the measured signals through an insulated conduit to state-of-the-art temperature-controlled electronics, eliminating the adverse influence of temperature variation on the electronics which is commonly found in competitive technology.
The heart of the Discovery DSC technology is the Diffusion-Bonded Sensor. To ensure highly-repeatable and stable measurements, the transducer is precision-mounted on a fixed pedestal. Unlike competitive designs where sensors are allowed to move, this pedestal mounting results in a stable configuration with a well-defined heat-flow path unaffected by thermal gradients. The result is unmatched precision and repeatability of the heat flow and temperature measurements.
Our innovative Gas-Delivery Module is standard on the Discovery DSC. The manifold design eliminates tubing and hardware connections which are prone to leaks, ensuring a highly consistent, repeatable inert atmosphere. For experiments which require dynamic or reactive atmospheres, software-controlled gas switching is also supported.
